+Basic Installation
+==================
+
+   These are generic installation instructions that apply to systems that
+can run the `configure' shell script - Unix systems and any that imitate
+it. They are not specific to xfpt.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+               51 Franklin Street, Fifth Floor, Boston, MA 02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+THE XFPT PLAIN TEXT TO XML PROCESSOR
+------------------------------------
+
+UNIX AND UNIX-LIKE SYSTEMS
+--------------------------
+
+It should just be a matter of typing
+
+  ./configure
+  make
+  make install
+
+to get youself an installed xfpt command. There is a man page that lists the
+command arguments. However, the main documentation is provided only as a PDF
+file in the doc directory. The xfpt source that was used to create the XML that
+in turn was used to generate the PDF is also included. You can get rid of xfpt
+by "make uninstall".
+
+
+OTHER SYSTEMS
+-------------
+
+xfpt consists almost entirely of Standard C code, and so it should be possible
+to compile it on any system with a Standard C compiler and library.

+.TH XFPT 1
+.SH NAME
+xfpt - make XML from plain text
+.SH SYNOPSIS
+.B xfpt [options] [source file]
+.
+.SH DESCRIPTION
+.rs
+.sp
+\fBxfpt\fP converts a marked up text file to XML. The markup is simple and
+consists of lines that begin with a dot ("directive lines") and sequences in
+the text that begin with an ampersand ("flags"). The flag sequences are not
+built-in, but are defined by directives. As well as the in-built directives,
+macros can be used to implement higher level concepts. A standard set of macros 
+and flags that generate DocBook XML is provided. There is a full description in
+the \fBxfpt\fP specification, which is distributed as a PDF file, an HTML file, 
+and as \Bxfpt\fP source.
+.
+.SH OPTIONS
+.rs
+.TP 10
+\fB-help\fP
+This causes \fBxfpt\fP to output its "usage" information and then exit.
+.TP
+\fB-o\fP \fIfile\fP
+This specifies the output file. The default is the standard output if no source 
+file is given, and the source file name with a \fI.xml\fP extension otherwise.
+.TP
+\fB-S\fP \fIdirectory\fP
+This specifies an alternative "share" directory in which to find standard 
+configuration files.

+<div class="chapter" lang="en" xml:lang="en"><div class="titlepage"><div><div><h2 class="title"><a href="#" id="id2490895">1. Introduction</a></h2></div></div></div><p><span class="emphasis"><em>xfpt</em></span> is a program that reads a marked-up ASCII source file, and converts it into
+XML. It was written with DocBook XML in mind, but can also be used for other
+forms of XML. Unlike <span class="emphasis"><em>AsciiDoc</em></span> (<span class="bold"><strong><a href="http://www.methods.co.nz/asciidoc/" target="_top">http://www.methods.co.nz/asciidoc/</a></strong></span>),
+<span class="emphasis"><em>xfpt</em></span> does not try to produce XML from a document that is also usable as a
+freestanding ASCII document. The input for <span class="emphasis"><em>xfpt</em></span> is very definitely “<span class="quote">marked
+up</span>�. This makes it less ambiguous for large and/or complicated documents. <span class="emphasis"><em>xfpt</em></span>
+is also much faster than <span class="emphasis"><em>AsciiDoc</em></span> because it is written in C and does not
+rely on pattern matching.
+</p><p>
+<span class="emphasis"><em>xfpt</em></span> is aimed at users who understand the XML that they are generating. It makes
+it easy to include literal XML, either in blocks, or within paragraphs. <span class="emphasis"><em>xfpt</em></span>
+restricts itself to two special characters that trigger all its processing.
+</p><p>
+<span class="emphasis"><em>xfpt</em></span> treats any input line that starts with a dot as a <span class="emphasis"><em>directive</em></span> line.
+Directives control the way the input is processed. A small number of directives
+are implemented in the program itself. A macro facility makes it possible to
+combine these in various ways to define directives for higher-level concepts
+such as chapters and sections. A standard macro library that generates a simple
+subset of DocBook XML is provided. The only XML element that the program itself
+generates is <code class="literal">&lt;para&gt;</code>; all the others must be included as literal XML, either
+directly in the input text, or, more commonly, as part of the text that is
+generated by a macro call.
+</p><p>
+The ampersand character is special within non-literal text that is processed by
+<span class="emphasis"><em>xfpt</em></span>. An ampersand introduces a <span class="emphasis"><em>flag sequence</em></span> that modifies the output.
+Ampersand was chosen because it is also special in XML. As well as recognizing
+flag sequences that begin with an ampersand, <span class="emphasis"><em>xfpt</em></span> converts grave accents and
+apostrophes that appear in non-literal text into typographic opening and
+closing quotes, as follows:
+</p><div class="literallayout">
+ <code class="literal"> `    </code>  becomes  ‘<br />
+ <code class="literal"> '    </code>  becomes  ’<br />
+</div><p>
+Within normal input text, ampersand, grave accent, and apostrophe are the only
+characters that cause <span class="emphasis"><em>xfpt</em></span> to change the input text, and this applies only to
+non-literal text. In literal text, there are no markup characters, and only a
+dot at the start of a line is recognized as special. Within the body of a
+macro, there is one more special character: the dollar character is used to
+introduce an argument substitution.
+</p><p>
+Notwithstanding the previous paragraph, <span class="emphasis"><em>xfpt</em></span> knows that it is generating XML,
+and in all cases when a literal ampersand or angle bracket is required in the
+output, the appropriate XML entity reference (<code class="literal">&amp;amp;</code>, <code class="literal">&amp;lt;</code>, or
+<code class="literal">&amp;gt;</code>, respectively) is generated.
+</p><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2453011">1.1 The <span xmlns="http://www.w3.org/1999/xhtml" class="emphasis"><em>xfpt</em></span> command line</a></h3></div></div></div><p>The format of the <span class="emphasis"><em>xfpt</em></span> command line is:
+</p><div class="literallayout">
+ <code class="literal">xfpt [</code><span class="emphasis"><em>options</em></span><code class="literal">] [</code><span class="emphasis"><em>input source</em></span><code class="literal">]</code><br />
+</div><p>
+If no input is specified, the standard input is read. There are three options:
+</p><div class="literallayout">
+ <code class="literal">-help</code><br />
+</div><p>
+This option causes <span class="emphasis"><em>xfpt</em></span> to output its “<span class="quote">usage</span>� message, and exit.  
+</p><div class="literallayout">
+ <code class="literal">-o </code><span class="emphasis"><em>&lt;output destination&gt;</em></span><br />
+</div><p>
+This option overrides the default destination. If the standard input is being
+read, the default destination is the standard output. Otherwise, the default
+destination is the name of the input file with the extension <em class="filename">.xml</em>,
+replacing its existing extension if there is one. A single hyphen character can
+be given as an output destination to refer to the standard output.
+</p><div class="literallayout">
+  <code class="literal">-S </code><span class="emphasis"><em>&lt;directory path&gt;</em></span><br />
+</div><p>
+This option overrides the path to <span class="emphasis"><em>xfpt</em></span>’s library directory that is built into
+the program. This makes it possible to use or test alternate libraries.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2454820">1.2 A short <span xmlns="http://www.w3.org/1999/xhtml" class="emphasis"><em>xfpt</em></span> example</a></h3></div></div></div><p>Here is a very short example of a complete <span class="emphasis"><em>xfpt</em></span> input file that uses some of the
+standard macros and flags:
+</p><pre class="literallayout">
+ .include stdflags
+ .include stdmacs
+ .docbook
+ .book
+
+ .chapter "The first chapter"
+ This is the text of the first chapter. Here is an &amp;'italic'&amp;
+ word, and here is a &amp;*bold*&amp; one.
+
+ .section "This is a section heading"
+ We can use the &amp;*ilist*&amp; macro to generate an itemized list:
+ .ilist
+ The first item in the list.
+ .next
+ The last item in the list.
+ .endlist
+
+ There are also standard macros for ordered lists, literal
+ layout blocks, code blocks, URL references, index entries
+ and tables.
+</pre></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="SECTliteralprocessing">1.3 Literal and non-literal processing</a></h3></div></div></div><p><span class="emphasis"><em>xfpt</em></span> processes non-directive input lines in one of four ways (known as
+“<span class="quote">modes</span>�):
+</p><div class="itemizedlist"><ul type="disc"><li><p>
+In the default mode, text is processed paragraph by paragraph. The end of a
+paragraph is indicated by the end of the input, a blank line, or by an
+occurrence of the <span class="bold"><strong>.literal</strong></span> directive. Other directives (for example,
+<span class="bold"><strong>.include</strong></span>) do not of themselves terminate a paragraph. Most of the standard
+macros (such as <span class="bold"><strong>.chapter</strong></span> and <span class="bold"><strong>.section</strong></span>) force a paragraph end by
+starting their contents with a <span class="bold"><strong>.literal</strong></span> directive.
+</p><p>
+Because <span class="emphasis"><em>xfpt</em></span> reads a whole paragraph before processing it, error messages
+contain the phrase “<span class="quote">detected near line <span class="emphasis"><em>nnn</em></span></span>�, where the line number is
+typically that of the last line of the paragraph.
+</p></li><li><p>
+In the “<span class="quote">literal layout</span>� mode, text is processed line by line, but is
+otherwise handled as in the default mode. The only real difference this makes
+to the markup from the user’s point of view is that paired flags must be on the
+same line. In this mode, error messages are more likely to contain the exact
+line number where the fault lies. Literal layout mode is used by the standard
+<span class="bold"><strong>.display</strong></span> macro to generate <code class="literal">&lt;literallayout&gt;</code> elements.
+</p></li><li><p>
+In the “<span class="quote">literal text</span>� mode, text is also processed line by line, but no flags
+are recognized. The only modification <span class="emphasis"><em>xfpt</em></span> makes to the text is to turn
+ampersand and angle bracket characters into XML entity references. This mode is
+used by the standard <span class="bold"><strong>.code</strong></span> macro to generate <code class="literal">&lt;literallayout&gt;</code> elements
+that include <code class="literal">class=monospaced</code>.
+</p></li><li><p>
+In the “<span class="quote">literal XML</span>� mode, text lines are copied to the output without
+modification. This is the easiest way to include a chunk of literal XML in the
+output. An example might be the <code class="literal">&lt;bookinfo&gt;</code> element, which occurs only once
+in a document. It is not worth setting up a macro for a one-off item like this.
+</p></li></ul></div><p>
+The <span class="bold"><strong>.literal</strong></span> directive switches between the modes. It is not normally used
+directly, but instead is incorported into appropriate macro definitions.
+</p><p>
+Directive lines are recognized and acted upon in all four modes. However, an
+unrecognized line that starts with a dot in the literal text or literal XML
+mode is treated as data. In the other modes, such a line provokes an error.
+</p><p>
+If you need to have a data line that begins with a dot in literal layout mode,
+you can either specify it by character number, or precede it with some
+non-acting markup. These two examples are both valid:
+</p><pre class="literallayout">
+ &amp;#x2e;start with a dot
+ &amp;''&amp;.start with a dot
+</pre><p>
+The second example assumes the standard flags are defined: it precedes the dot 
+with an empty italic string. However, this is untidy because the empty string
+will be carried over into the XML.
+</p><p>
+In literal text or literal XML mode, it is not possible to have a data line
+that starts with a dot followed by the name of a directive or macro. You have
+to use literal layout mode if you require such output. Another solution, which
+is used in the source for this document (where many examples show directive
+lines), is to indent every displayed line by one space, and thereby avoid the
+problem altogether.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2453241">1.4 Format of directive lines</a></h3></div></div></div><p>If an input line starts with a dot followed by a space, it is ignored by <span class="emphasis"><em>xfpt</em></span>.
+This provides a facility for including comments in the input. Otherwise, the
+dot must be followed by a directive or macro name, and possibly one or more
+arguments. Arguments that are strings are delimited by white space unless they
+are enclosed in single or double quotes. The delimiting quote character can be
+included within a quoted string by doubling it. Here are some examples:
+</p><pre class="literallayout">
+ .literal layout
+ .set version 0.00
+ .row "Jack's house" 'Jill''s house'
+</pre><p>
+An unrecognized directive line normally causes an error; however, in the
+literal text and literal XML modes, an unrecognized line that starts with a
+dot is treated as a data line.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="SECTcallingmacro">1.5 Calling macros</a></h3></div></div></div><p>Macros are defined by the <span class="bold"><strong>.macro</strong></span> directive, which is described in section
+<a href="#SECTmacro" title="3.9&#xA0;The .macro directive">3.9</a>. There are two ways of calling a macro. It can be called in the
+same way as a directive, or it can be called from within text that is being
+processed. The second case is called an “<span class="quote">inline macro call</span>�.
+</p><p>
+When a macro is called as a directive, its name is given after a dot at the
+start of a line, and the name may be followed by any number of optional
+arguments, in the same way as a built-in directive (see the previous section).
+For example:
+</p><pre class="literallayout">
+ .chapter "Chapter title" chapter-reference
+</pre><p>
+The contents of the macro, after argument substitution, are processed in
+exactly the same way as normal input lines. A macro that is called as a 
+directive may contain nested macro calls.
+</p><p>
+When a macro is called from within a text string, its name is given after an
+ampersand, and is followed by an opening parenthesis. Arguments, delimited by
+commas, can then follow, up to a closing parenthesis. If an argument contains a
+comma or a closing parenthesis, it must be quoted. White space after a
+separating comma is ignored. The most common example of this type of macro
+call is the standard macro for generating a URL reference:
+</p><pre class="literallayout">
+ Refer to a URL via &amp;url(http://x.example,this text).
+</pre><p>
+There are differences in the behaviour of macros, depending on which way they
+are called. A macro that is called inline may not contain references to other
+macros; it must contain only text lines and calls to built-in directives.
+Also, newlines that terminate text lines within the macro are not included in
+the output.
+</p><p>
+A macro that can be called inline can always be called as a directive, but the
+opposite is not always true. Macros are usually designed to be called either
+one way or the other. However, the <span class="bold"><strong>.new</strong></span> and <span class="bold"><strong>.index</strong></span> macros in the
+standard library are examples of macros that are designed be called either way.

+unmodified. The number can be decimal, or hexadecimal preceded by <code class="literal">x</code>. For

+<span class="bold"><strong>.flag</strong></span> directive. These are of two types, standalone and paired. Both cases
+define replacement text. This is always literal; it is not itself scanned for
+flag occurrences.
+</p><p>
+Lines are scanned from left to right when flags are being interpreted. If
+there is any ambiguity when a text string is being scanned, the longest flag
+sequence wins. Thus, it is possible (as in the standard flag sequences) to
+define both <code class="literal">&amp;&lt;</code> and <code class="literal">&amp;&lt;&lt;</code> as flags, provided that you never want to
+follow the first of them with a <code class="literal">&lt;</code> character.
+</p><p>
+You can define flags that start with <code class="literal">&amp;#</code>, but these must be used with care,
+lest they be misinterpreted as numerical references to XML entities.
+</p><p>
+A standalone flag consists of an ampersand followed by any number of
+non-alphanumeric characters. When it is encountered, it is replaced by its
+replacement text. For example, in the standard flag definitions, <code class="literal">&amp;&amp;</code>
+is defined as a standalone flag with with the replacement text <code class="literal">&amp;amp;</code>.
+</p><p>
+A paired flag is defined as two sequences. The first takes the same form as a
+standalone flag. The second also consists of non-alphanumeric characters, but
+need not start with an ampersand. It is often defined as the reverse of the
+first sequence. When the first sequence of a paired flag is encountered, its
+partner is expected to be found within the same paragraph (or line, in literal
+layout mode). Furthermore, multiple occurrences of paired flags must be
+correctly nested. For example, in the standard definitions, <code class="literal">&amp;'</code> and
+<code class="literal">'&amp;</code> are defined as a flag pair for enclosing text in an <code class="literal">&lt;emphasis&gt;</code>
+element. Each member of the pair is replaced by its replacement text.
+</p><p>
+Note that, though <span class="emphasis"><em>xfpt</em></span> diagnoses an error for badly nested flag pairs, it does
+not prevent you from generating invalid XML. For example, DocBook does not
+allow <code class="literal">&lt;emphasis&gt;</code> within <code class="literal">&lt;literal&gt;</code>, though it does allow <code class="literal">&lt;literal&gt;</code>

+The following lines, up to <span class="bold"><strong>.endmacro</strong></span>, form the body of the macro. They are
+not processed in any way when the macro is defined; they are processed only
+when the macro is called (see section <a href="#SECTcallingmacro" title="1.5&#xA0;Calling macros">1.5</a>).
+</p><p>
+Within the body of a macro, argument substitutions can be specified by means of
+a dollar character and an argument number, for example, <code class="literal">$3</code> for the third
+argument. See also <span class="bold"><strong>.eacharg</strong></span> above for the use of <code class="literal">$+</code> to refer to
+relative arguments when looping through them. A reference to an argument that
+is not supplied, and is not given a default, results in an empty substitution.
+</p><p>
+There is also a facility for a conditional substitution. A reference to an
+argument of the form:
+</p><div class="literallayout">
+<code class="literal">$=</code><span class="emphasis"><em>&lt;digits&gt;&lt;delimiter&gt;&lt;text&gt;&lt;delimiter&gt;</em></span><br />
+</div><p>
+inserts the text if the argument is defined and is not an empty string, and
+nothing otherwise. The text is itself scanned for flags and argument
+substitutions. The delimiter must be a single character that does not appear in
+the text. For example:
+</p><pre class="literallayout">
+&amp;&lt;chapter$=2+ id="$2"+&gt;&amp;
+</pre><p>
+If this appears in a macro that is called with only one argument, the result
+is:
+</p><pre class="literallayout">
+&lt;chapter&gt;
+</pre><p>
+but if the second argument is, say <code class="literal">abcd</code>, the result is:
+</p><pre class="literallayout">
+&lt;chapter id="abcd"&gt;
+</pre><p>
+This conditional feature can be used with both absolute and relative argument
+references.
+</p><p>
+If a dollar character is required as data within the body of a macro, it must 
+be doubled. For example:
+</p><pre class="literallayout">
+  .macro price
+  The price is $$1.
+  .endmacro
+</pre><p>
+If you redefine an existing macro, the new definition overrides the old. There
+is no way to revert to the previous definition. If you define a macro whose 
+name is the same as the name of a built-in directive you will not be able to 
+call it, because <span class="emphasis"><em>xfpt</em></span> looks for built-in directives before it looks for macros.
+</p><p>
+It is possible to define a macro within a macro, though clearly care must be 
+taken with argument references to ensure that substitutions happen at the right
+level.

+<span class="emphasis"><em>xfpt</em></span>’s library. This may be extended as experience with <span class="emphasis"><em>xfpt</em></span> accumulates. The
+standard macros assume that the standard flags are defined, so a document that
+is going to use these features should start with:
+</p><pre class="literallayout">
+ .include stdflags
+ .include stdmacs
+</pre><p>
+All the standard macros except <span class="bold"><strong>new</strong></span>, <span class="bold"><strong>index</strong></span>, and <span class="bold"><strong>url</strong></span> are intended to
+be called as directive lines. Their names are therefore shown with a leading
+dot in the discussion below.
+</p><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2501671">4.1 Overall setup</a></h3></div></div></div><p>There are two macros that should be used only once, at the start of the
+document. The <span class="bold"><strong>.docbook</strong></span> macro has no arguments. It inserts into the output
+file the standard header material for a DocBook XML file, which is:
+</p><pre class="literallayout">
+&lt;?xml version="1.0" encoding="UTF-8"?&gt;
+&lt;!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
+"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"&gt;
+</pre><p>
+The <span class="bold"><strong>.book</strong></span> macro has no arguments. It generates <code class="literal">&lt;book&gt;</code> and pushes
+<code class="literal">&lt;/book&gt;</code> onto the stack so that it will be output at the end.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2501728">4.2 Chapters, sections, and subsections</a></h3></div></div></div><p>Chapters, sections, and subsections are supported by three macros that all
+operate in the same way. They are <span class="bold"><strong>.chapter</strong></span>, <span class="bold"><strong>.section</strong></span>, and
+<span class="bold"><strong>.subsection</strong></span>. They take either one, two, or three arguments. The first
+argument is the title. If a second argument is present, and is not an empty
+string, it is set as an ID, and can be used in cross-references. For example:
+</p><pre class="literallayout">
+ .chapter "Introduction"
+</pre><p>
+sets no ID, but
+</p><pre class="literallayout">
+ .section "A section title" "SECTdemo"
+</pre><p>
+can be referenced from elsewhere in the document by a phrase such as:
+</p><pre class="literallayout">
+ see section &amp;&lt;&lt;SECTdemo&gt;&gt;&amp;
+</pre><p>
+When the title of a chapter of section is being used as a running head or foot 
+(for example), it may be too long to fit comfortably into the available space. 
+DocBook provides the facility for a title abbreviation to be specified to deal
+with this problem. If a third argument is given to one of these macros, it
+causes a <code class="literal">&lt;titleabbrev&gt;</code> element to be generated. In this case, a second
+argument must also be provided, but if you do not need an ID, the second
+argument can be an empty string. For example:
+</p><pre class="literallayout">
+  .chapter "This chapter has quite a long title" "" "Long title"
+</pre><p>
+Where and when the abbreviation is used in place of the full title is
+controlled by the stylesheet when the XML is processed.
+</p><p>
+These three macros use the stack to ensure that each chapter, section, and
+subsection is terminated at the correct point. For example, starting a new
+section automatically terminates an open subsection and a previous section.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2501835">4.3 URL references</a></h3></div></div></div><p>The <span class="bold"><strong>url</strong></span> macro generates URL references, and is intended to be called inline
+within the text that is being processed. It generates a <code class="literal">&lt;ulink&gt;</code> element,
+and has either one or two arguments. The first argument is the URL, and the
+second is the text that describes it. For example:
+</p><pre class="literallayout">
+ More details are &amp;url(http://x.example, here).
+</pre><p>
+This generates the following XML:
+</p><pre class="literallayout">
+ More details are &lt;ulink url="http://x.example"&gt;here&lt;/ulink&gt;.
+</pre><p>
+If the second argument is absent, the contents of the first argument are used
+instead. If <span class="bold"><strong>url</strong></span> is called as a directive, there will be a newline in the 
+output after <code class="literal">&lt;/ulink&gt;</code>, which in most cases (such as the example above), you 
+do not want.

+are normally rendered with bullets or similar markings. The macro can
+optionally be called with one argument, for which there is no default. If the
+argument is present, it is used to add a <code class="literal">mark=</code> attribute to the
+<code class="literal">&lt;itemizedlist&gt;</code> element that is generated. The mark names that can be used
+depend on the software that processes the resulting XML. For HTML output,
+“<span class="quote">square</span>� and “<span class="quote">opencircle</span>� work in some browsers.
+</p><p>
+The text for the first item follows the macro call. The start of the next item
+is indicated by the <span class="bold"><strong>.next</strong></span> macro, and the end of the list by <span class="bold"><strong>.endlist</strong></span>.
+For example:
+</p><pre class="literallayout">
+ .ilist
+ This is the first item.

+numbered. If no argument is given, arabic numerals are used. One of the
+following words can be given as the macro’s argument to specify the numeration:
+</p><div class="literallayout">
+<code class="literal">arabic     </code>   arabic numerals<br />
+<code class="literal">loweralpha </code>   lower case letters<br />

+</div><p>
+The text for the first item follows the macro call. The start of the next item
+is indicated by the <span class="bold"><strong>.next</strong></span> macro, and the end of the list by <span class="bold"><strong>.endlist</strong></span>.

+</p><pre class="literallayout">

+terms and an associated description. Typically, the terms are printed in a
+style that makes them stand out, and the description is indented underneath.
+The start of a variable list is indicated by the <span class="bold"><strong>.vlist</strong></span> macro, which has
+one optional argument. If present, it defines a title for the list.
+</p><p>
+Each entry is defined by a <span class="bold"><strong>.vitem</strong></span> macro, whose arguments are the terms.
+This is followed by the body of the entry. The list is terminated by the
+<span class="bold"><strong>.endlist</strong></span> macro. For example:
+</p><pre class="literallayout">
+ .vlist "Font filename extensions"
+ .vitem "TTF"
+ TrueType fonts.
+ .vitem "PFA" "PFB"
+ PostScript fonts.
+ .endlist

Some DocBook processors automatically choose
+different bullets for nested itemized lists, but others do not. The
+<span class="bold"><strong>.endlist</strong></span> macro has no useful arguments. Any text that follows it is
+treated as a comment. This can provide an annotation facility that may make the
+input easier to understand when lists are nested.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2502147">4.8 Displayed text</a></h3></div></div></div><p>In displayed text each non-directive input line generates one output line. The
+<code class="literal">&lt;literallayout&gt;</code> DocBook element is used to achieve this. Two kinds of
+displayed text are supported by the standard macros. They differ in their
+handling of the text itself.
+</p><p>
+The macro <span class="bold"><strong>.display</strong></span> is followed by lines that are processed in the same way
+as normal paragraphs: flags are interpreted, and so there may be font changes
+and so on. The lines are processed in literal layout mode. For example:
+</p><pre class="literallayout">
+ .display
+ &amp;`-o`&amp;   set output destination
+ &amp;`-S`&amp;   set library path
+ .endd
+</pre><p>
+The output is as follows:
+</p><div class="literallayout">
+ <code class="literal">-o</code>   set output destination<br />
+ <code class="literal">-S</code>   set library path<br />
+</div><p>
+The macro <span class="bold"><strong>.code</strong></span> is followed lines that are not processed in any way, except
+to turn ampersands and angle brackets into XML entities. The lines are
+processed in literal text mode. In addition, <code class="literal">class="monospaced"</code> is added to
+the <code class="literal">&lt;literallayout&gt;</code> element, so that the lines are displayed in a
+monospaced font. For example:
+</p><pre class="literallayout">
+ .code
+ z = sqrt(x*x + y*y);
+ .endd
+</pre><p>
+As the examples illustrate, both kinds of display are terminated by the
+<span class="bold"><strong>.endd</strong></span> macro.

+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="SECTrevmacs">4.10 Revision markings</a></h3></div></div></div><p>Two macros are provided to simplify setting and unsetting the “<span class="quote">changed</span>�
+revision marking (see section <a href="#SECTrevision" title="3.12&#xA0;The .revision directive">3.12</a>). When the revised text is
+substantial (for example, a complete paragraph, table, display, or section), it
+can be placed between <span class="bold"><strong>.new</strong></span> and <span class="bold"><strong>.wen</strong></span>, as in this example:
+</p><pre class="literallayout">
+  This paragraph is not flagged as changed.
+  .new
+  This is a changed paragraph that contains a display:
+  .display
+  whatever
+  .endd
+  This is the next paragraph.
+  .wen      
+  Here is the next, unmarked, paragraph.
+</pre><p>
+When called like this, without an argument, <span class="bold"><strong>.new</strong></span> terminates the current
+paragraph, and <span class="bold"><strong>.wen</strong></span> always does so. Therefore, even though there are no
+blank lines before <span class="bold"><strong>.new</strong></span> or <span class="bold"><strong>.wen</strong></span> above, the revised text will end up in
+a paragraph of its own. (You can, of course, put in blank lines if you wish.)
+</p><p>
+If want to indicate that just a few words inside a paragraph are revised, you
+can call the <span class="bold"><strong>new</strong></span> macro with an argument. The macro can be called either as
+a directive or inline:
+</p><pre class="literallayout">
+  This is a paragraph that has 
+  .new "a few marked words" 
+  within it. Here are &amp;new(some more) marked words.
+</pre><p>
+The effect of this is to generate a <code class="literal">&lt;phrase&gt;</code> XML element with the
+<code class="literal">revisionflag</code> attribute set. The <span class="bold"><strong>.wen</strong></span> macro is not used in this case.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2502417">4.11 Informal tables</a></h3></div></div></div><p>The <span class="bold"><strong>.itable</strong></span> macro starts an informal (untitled) table with some basic
+parameterization. If you are working on a large document that has many tables
+with the same parameters, the best approach is to define your own table macros,
+possibly calling the standard one with specific arguments.
+</p><p>
+The <span class="bold"><strong>.itable</strong></span> macro has four basic arguments:
+</p><div class="orderedlist"><ol type="1"><li><p>
+The frame requirement for the table, which may be one of the words “<span class="quote">all</span>�,
+“<span class="quote">bottom</span>�, “<span class="quote">none</span>� (the default), “<span class="quote">sides</span>�, “<span class="quote">top</span>�, or “<span class="quote">topbot</span>�.
+</p></li><li><p>
+The “<span class="quote">colsep</span>� value for the table. The default is “<span class="quote">0</span>�, meaning no vertical
+separator lines between columns. The value “<span class="quote">1</span>� requests vertical separator
+lines.
+</p></li><li><p>
+The “<span class="quote">rowsep</span>� value for the table. The default is “<span class="quote">0</span>�, meaning no horizontal
+lines between rows. The value “<span class="quote">1</span>� requests horizontal separator lines.
+</p></li><li><p>
+The number of columns.
+</p></li></ol></div><p>
+These arguments must be followed by two arguments for each column. The first
+specifies the column width, and the second its aligmnent. A column width can be
+specified as an absolute dimension such as 36pt or 2in, or as a proportional
+measure, which has the form of a number followed by an asterisk. The two forms
+can be mixed – see the DocBook specification for details.
+</p><p>
+Straightforward column alignments can be specified as “<span class="quote">center</span>�, “<span class="quote">left</span>�, or
+“<span class="quote">right</span>�. DocBook also has some other possibilities, but sadly they do not 
+seem to include “<span class="quote">centre</span>�.
+</p><p>
+Each row of the table is specified using a <span class="bold"><strong>.row</strong></span> macro; the entries in
+the row are the macros’s arguments. The table is terminated by <span class="bold"><strong>.endtable</strong></span>,
+which has no arguments. For example:
+</p><pre class="literallayout">
+ .itable all 1 1 2 1in left 2in center
+ .row "cell 11" "cell 12"
+ .row "cell 21" "cell 22"
+ .endtable
+</pre><p>
+This specifies a framed table, with both column and row separator lines. There
+are two columns: the first is one inch wide and left aligned, and the second is
+two inches wide and centred. There are two rows. The output looks like this:
+</p><div class="informaltable"><table border="1"><colgroup><col align="left" /><col align="center" /></colgroup><tbody><tr><td align="left">cell 11</td><td align="center">cell 12</td></tr><tr><td align="left">cell 21</td><td align="center">cell 22</td></tr></tbody></table></div><p>
+The <span class="bold"><strong>.row</strong></span> macro does not set the <code class="literal">revisionflag</code> attribute in the 
+<code class="literal">&lt;entry&gt;</code> elements that it generates because this appears to be ignored by 
+all current XML processors. However, you can use an inline call of the <span class="bold"><strong>new</strong></span> 
+macro within an entry to generate a <code class="literal">&lt;phrase&gt;</code> element with <code class="literal">revisionflag</code> 
+set.
+</p></div><div class="section" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 xmlns="" class="title"><a xmlns="http://www.w3.org/1999/xhtml" href="#" id="id2502692">4.12 Indexes</a></h3></div></div></div><p>The <span class="bold"><strong>.index</strong></span> macro generates <code class="literal">&lt;indexterm&gt;</code> elements (index entries) in the
+output. It takes one or two arguments. The first is the text for the primary
+index term, and the second, if present, specifies a secondary index term. This
+macro can be called either from a directive line, or inline. However, it is
+mostly called as a directive, at the start of a relevant paragraph. For
+example:
+</p><pre class="literallayout">
+ .index goose "wild chase"
+ The chasing of wild geese...
+</pre><p>
+The <span class="bold"><strong>.makeindex</strong></span> macro should be called at the end of the document, at the
+point where you want an index to be generated. It can have up to two
+arguments. The first is the title for the index, for which the default is
+“<span class="quote">Index</span>�. The second, if present, causes a <code class="literal">role=</code> attribute to be added to
+the <code class="literal">&lt;index&gt;</code> element that is generated. For this to be useful, you need to
+generate <code class="literal">&lt;indexterm&gt;</code> elements that have similar <code class="literal">role=</code> attributes. The
+standard <span class="bold"><strong>index</strong></span> macro cannot do this. If you want to generate multiple
+indexes using this mechanism, it is best to define your own macros for each
+index type. For example:
+</p><pre class="literallayout">
+ .macro cindex
+ &amp;&lt;indexterm role="concept"&gt;&amp;
+ &amp;&lt;primary&gt;&amp;$1&amp;&lt;/primary&gt;&amp;
+ .arg 2
+ &amp;&lt;secondary&gt;&amp;$2&amp;&lt;/secondary&gt;&amp;
+ .endarg
+ &amp;&lt;/indexterm&gt;&amp;
+ .endmacro
+</pre><p>
+This defines a <span class="bold"><strong>.cindex</strong></span> macro for the “<span class="quote">concept</span>� index. At the end of the 
+document you might have:
+</p><pre class="literallayout">
+ .makeindex "Concept index" "concept"
+ .makeindex
+</pre><p>
+As long as the processing software can handle multiple indexes, this causes two
+indexes to be generated. The first is entitled “<span class="quote">Concept index</span>�, and contains 
+only those index entries that were generated by the <span class="bold"><strong>.cindex</strong></span> macro. The 
+second contains all index entries.
+</p></div></div></div></body></html>

+.chapter "Introduction"
+&X; is a program that reads a marked-up ASCII source file, and converts it into
+XML. It was written with DocBook XML in mind, but can also be used for other
+forms of XML. Unlike &'AsciiDoc'& (&url(http://www.methods.co.nz/asciidoc/)),
+&X; does not try to produce XML from a document that is also usable as a
+freestanding ASCII document. The input for &X; is very definitely &"marked
+up"&. This makes it less ambiguous for large and/or complicated documents. &X;
+is also much faster than &'AsciiDoc'& because it is written in C and does not
+rely on pattern matching.
+
+&X; is aimed at users who understand the XML that they are generating. It makes
+it easy to include literal XML, either in blocks, or within paragraphs. &X;
+restricts itself to two special characters that trigger all its processing.
+
+&X; treats any input line that starts with a dot as a &'directive'& line.
+Directives control the way the input is processed. A small number of directives
+are implemented in the program itself. A macro facility makes it possible to
+combine these in various ways to define directives for higher-level concepts
+such as chapters and sections. A standard macro library that generates a simple
+subset of DocBook XML is provided. The only XML element that the program itself
+generates is &`<para>`&; all the others must be included as literal XML, either
+directly in the input text, or, more commonly, as part of the text that is
+generated by a macro call.
+
+The ampersand character is special within non-literal text that is processed by
+&X;. An ampersand introduces a &'flag sequence'& that modifies the output.
+Ampersand was chosen because it is also special in XML. As well as recognizing
+flag sequences that begin with an ampersand, &X; converts grave accents and
+apostrophes that appear in non-literal text into typographic opening and
+closing quotes, as follows:
+
+.display
+ &`&nbsp;&#x60;    `&  becomes &nbsp;`
+ &`&nbsp;&#x27;    `&  becomes &nbsp;'
+.endd
+
+Within normal input text, ampersand, grave accent, and apostrophe are the only
+characters that cause &X; to change the input text, and this applies only to
+non-literal text. In literal text, there are no markup characters, and only a
+dot at the start of a line is recognized as special. Within the body of a
+macro, there is one more special character: the dollar character is used to
+introduce an argument substitution.
+
+Notwithstanding the previous paragraph, &X; knows that it is generating XML,
+and in all cases when a literal ampersand or angle bracket is required in the
+output, the appropriate XML entity reference (&`&&amp;`&, &`&&lt;`&, or
+&`&&gt;`&, respectively) is generated.
+
+
+.section "The &X; command line"
+The format of the &X; command line is:
+.display
+ &`xfpt [`&&'options'&&`] [`&&'input source'&&`]`&
+.endd
+If no input is specified, the standard input is read. There are three options:
+.display
+ &`-help`&
+.endd
+This option causes &X; to output its &"usage"& message, and exit.  
+  
+.display
+ &`-o `&&'<output destination>'&
+.endd
+This option overrides the default destination. If the standard input is being
+read, the default destination is the standard output. Otherwise, the default
+destination is the name of the input file with the extension &_.xml_&,
+replacing its existing extension if there is one. A single hyphen character can
+be given as an output destination to refer to the standard output.
+.display
+  &`-S `&&'<directory path>'&
+.endd
+This option overrides the path to &X;'s library directory that is built into
+the program. This makes it possible to use or test alternate libraries.
+
+
+.section "A short &X; example"
+Here is a very short example of a complete &X; input file that uses some of the
+standard macros and flags:
+.code
+ .include stdflags
+ .include stdmacs
+ .docbook
+ .book
+
+ .chapter "The first chapter"
+ This is the text of the first chapter. Here is an &'italic'&
+ word, and here is a &*bold*& one.
+
+ .section "This is a section heading"
+ We can use the &*ilist*& macro to generate an itemized list:
+ .ilist
+ The first item in the list.
+ .next
+ The last item in the list.
+ .endlist
+
+ There are also standard macros for ordered lists, literal
+ layout blocks, code blocks, URL references, index entries
+ and tables.
+.endd
+
+
+
+.section "Literal and non-literal processing" "SECTliteralprocessing"
+&X; processes non-directive input lines in one of four ways (known as
+&"modes"&):
+
+.ilist
+In the default mode, text is processed paragraph by paragraph. The end of a
+paragraph is indicated by the end of the input, a blank line, or by an
+occurrence of the &*.literal*& directive. Other directives (for example,
+&*.include*&) do not of themselves terminate a paragraph. Most of the standard
+macros (such as &*.chapter*& and &*.section*&) force a paragraph end by
+starting their contents with a &*.literal*& directive.
+
+Because &X; reads a whole paragraph before processing it, error messages
+contain the phrase &"detected near line &'nnn'&"&, where the line number is
+typically that of the last line of the paragraph.
+
+.next
+In the &"literal layout"& mode, text is processed line by line, but is
+otherwise handled as in the default mode. The only real difference this makes
+to the markup from the user's point of view is that paired flags must be on the
+same line. In this mode, error messages are more likely to contain the exact
+line number where the fault lies. Literal layout mode is used by the standard
+&*.display*& macro to generate &`<literallayout>`& elements.
+
+.next
+In the &"literal text"& mode, text is also processed line by line, but no flags
+are recognized. The only modification &X; makes to the text is to turn
+ampersand and angle bracket characters into XML entity references. This mode is
+used by the standard &*.code*& macro to generate &`<literallayout>`& elements
+that include &`class=monospaced`&.
+
+.next
+In the &"literal XML"& mode, text lines are copied to the output without
+modification. This is the easiest way to include a chunk of literal XML in the
+output. An example might be the &`<bookinfo>`& element, which occurs only once
+in a document. It is not worth setting up a macro for a one-off item like this.
+.endlist
+
+The &*.literal*& directive switches between the modes. It is not normally used
+directly, but instead is incorported into appropriate macro definitions.
+
+Directive lines are recognized and acted upon in all four modes. However, an
+unrecognized line that starts with a dot in the literal text or literal XML
+mode is treated as data. In the other modes, such a line provokes an error.
+
+If you need to have a data line that begins with a dot in literal layout mode,
+you can either specify it by character number, or precede it with some
+non-acting markup. These two examples are both valid:
+.code
+ &#x2e;start with a dot
+ &''&.start with a dot
+.endd    
+The second example assumes the standard flags are defined: it precedes the dot 
+with an empty italic string. However, this is untidy because the empty string
+will be carried over into the XML.
+
+In literal text or literal XML mode, it is not possible to have a data line
+that starts with a dot followed by the name of a directive or macro. You have
+to use literal layout mode if you require such output. Another solution, which
+is used in the source for this document (where many examples show directive
+lines), is to indent every displayed line by one space, and thereby avoid the
+problem altogether.
+
+
+.section "Format of directive lines"
+If an input line starts with a dot followed by a space, it is ignored by &X;.
+This provides a facility for including comments in the input. Otherwise, the
+dot must be followed by a directive or macro name, and possibly one or more
+arguments. Arguments that are strings are delimited by white space unless they
+are enclosed in single or double quotes. The delimiting quote character can be
+included within a quoted string by doubling it. Here are some examples:
+.code
+ .literal layout
+ .set version 0.00
+ .row "Jack's house" 'Jill''s house'
+.endd
+An unrecognized directive line normally causes an error; however, in the
+literal text and literal XML modes, an unrecognized line that starts with a
+dot is treated as a data line.
+
+
+
+.section "Calling macros" "SECTcallingmacro"
+Macros are defined by the &*.macro*& directive, which is described in section
+&<<SECTmacro>>&. There are two ways of calling a macro. It can be called in the
+same way as a directive, or it can be called from within text that is being
+processed. The second case is called an &"inline macro call"&.
+
+When a macro is called as a directive, its name is given after a dot at the
+start of a line, and the name may be followed by any number of optional
+arguments, in the same way as a built-in directive (see the previous section).
+For example:
+.code
+ .chapter "Chapter title" chapter-reference
+.endd
+The contents of the macro, after argument substitution, are processed in
+exactly the same way as normal input lines. A macro that is called as a 
+directive may contain nested macro calls.
+
+When a macro is called from within a text string, its name is given after an
+ampersand, and is followed by an opening parenthesis. Arguments, delimited by
+commas, can then follow, up to a closing parenthesis. If an argument contains a
+comma or a closing parenthesis, it must be quoted. White space after a
+separating comma is ignored. The most common example of this type of macro
+call is the standard macro for generating a URL reference:
+.code
+ Refer to a URL via &url(http://x.example,this text).
+.endd
+
+There are differences in the behaviour of macros, depending on which way they
+are called. A macro that is called inline may not contain references to other
+macros; it must contain only text lines and calls to built-in directives.
+Also, newlines that terminate text lines within the macro are not included in
+the output.
+
+A macro that can be called inline can always be called as a directive, but the
+opposite is not always true. Macros are usually designed to be called either
+one way or the other. However, the &*.new*& and &*.index*& macros in the
+standard library are examples of macros that are designed be called either way.
+
+
+
+
+
+. ----------------------------------------------------------------------------
+.chapter "Flag sequences"
+Only one flag sequence is built-into the code itself. If an input line ends
+with three ampersands (ignoring trailing white space), the ampersands are
+removed, and the next input line, with any leading white space removed, is
+joined to the original line. This happens before any other processing, and may
+involve any number of lines. Thus:
+
+.display
+ &`The quick &amp;&amp;&amp;`&
+ &`    brown &amp;&amp;&amp;`&
+ &`      fox.`&
+.endd
+
+produces exactly the same output as:
+
+.code
+ The quick brown fox.
+.endd
+
+
+.section "Flag sequences for XML entities and &X; variables"
+If an ampersand is followed by a # character, a number, and a semicolon, it is
+understood as a numerical reference to an XML entity, and is passed through
+unmodified. The number can be decimal, or hexadecimal preceded by &`x`&. For
+example:
+.code
+ This is an Ohm sign: &#x2126;.
+ This is a degree sign: &#176;.
+.endd
+If an ampersand is followed by a letter, a sequence of letters, digits, and
+dots is read. If this is terminated by a semicolon, the characters between the
+ampersand and the semicolon are interpreted as an entity name. This can be:
+.ilist
+The name of an inbuilt &X; variable. At present, there is only one of these,
+called &`xfpt.rev`&. Its use is described with the &*.revision*& directive
+below.
+.next
+The name of a user variable that has been set by the &*.set*& directive, also
+described below.
+.next
+The name of an XML entity. This is assumed if the name is not recognized as one
+of the previous types. In this case, the input text is passed to the output
+without modification. For example:
+.code
+ This is an Ohm sign: &Ohm;.
+.endd
+.endlist
+
+
+.section "Flag sequences for calling macros"
+If an ampersand is followed by a sequence of alphanumeric characters starting
+with a letter, terminated by an opening parenthesis, the characters between the
+ampersand and the parenthesis are interpreted as the name of a macro. See
+section &<<SECTcallingmacro>>& for more details.
+
+
+
+.section "Other flag sequences"
+Any other flag sequences that are needed must be defined by means of the
+&*.flag*& directive. These are of two types, standalone and paired. Both cases
+define replacement text. This is always literal; it is not itself scanned for
+flag occurrences.
+
+Lines are scanned from left to right when flags are being interpreted. If
+there is any ambiguity when a text string is being scanned, the longest flag
+sequence wins. Thus, it is possible (as in the standard flag sequences) to
+define both &`&&<`& and &`&&<<`& as flags, provided that you never want to
+follow the first of them with a &`<`& character.
+
+You can define flags that start with &`&&#`&, but these must be used with care,
+lest they be misinterpreted as numerical references to XML entities.
+
+A standalone flag consists of an ampersand followed by any number of
+non-alphanumeric characters. When it is encountered, it is replaced by its
+replacement text. For example, in the standard flag definitions, &`&&&&`&
+is defined as a standalone flag with with the replacement text &`&&amp;`&.
+
+A paired flag is defined as two sequences. The first takes the same form as a
+standalone flag. The second also consists of non-alphanumeric characters, but
+need not start with an ampersand. It is often defined as the reverse of the
+first sequence. When the first sequence of a paired flag is encountered, its
+partner is expected to be found within the same paragraph (or line, in literal
+layout mode). Furthermore, multiple occurrences of paired flags must be
+correctly nested. For example, in the standard definitions, &`&&&#x27;`& and
+&`&#x27;&&`& are defined as a flag pair for enclosing text in an &`<emphasis>`&
+element. Each member of the pair is replaced by its replacement text.
+
+Note that, though &X; diagnoses an error for badly nested flag pairs, it does
+not prevent you from generating invalid XML. For example, DocBook does not
+allow &`<emphasis>`& within &`<literal>`&, though it does allow &`<literal>`&
+within &`<emphasis>`&.
+
+.section "Unrecognized flag sequences"
+If an ampersand is not followed by a character sequence in one of the forms
+described in the preceding sections, an error occurs.
+
+
+.section "Standard flag sequences"
+These are the standalone flag sequences that are defined in the &_stdflags_&
+file in the &X; library:
+.display
+ &`&&&&        `& becomes &` &&amp;`& (ampersand)
+ &`&&--       `& becomes &` &&ndash;`& (en-dash)
+ &`&&~        `& becomes &` &&nbsp;`& (`hard' space)
+.endd
+These are the flag pairs that are defined in the &_stdflags_& file in the &X;
+library:
+.display
+ &`&&"..."&&   `& becomes &`<quote>...</quote>`&
+ &`&&&#x27;...&#x27;&&   `& becomes &`<emphasis>...</emphasis>`&
+ &`&&*...*&&   `& becomes &`<emphasis role="bold">...</emphasis>`&
+ &`&&&#x60;...&#x60;&&   `& becomes &`<literal>...</literal>`&
+ &`&&_..._&&   `& becomes &`<filename>...</filename>`&
+ &`&&(...)&&   `& becomes &`<command>...</command>`&
+ &`&&[...]&&   `& becomes &`<function>...</function>`&
+ &`&&%...%&&   `& becomes &`<option>...</option>`&
+ &`&&$...$&&   `& becomes &`<varname>...</varname>`&
+ &`&&<...>&&   `& becomes &`<...>`&
+ &`&&<<...>>&& `& becomes &`<xref linkend="..."/>`&
+.endd
+For example, if you want to include a literal XML element in your output, you
+can do it like this: &`&&<element>&&`&. If you want to include a longer
+sequence of literal XML, changing to the literal XML mode may be more
+convenient.
+
+
+
+
+. ----------------------------------------------------------------------------
+.chapter "Built-in directive processing"
+The directives that are built into the code of &X; are now described in
+alphabetical order. You can see more examples of their use in the definitions
+of the standard macros in chapter &<<CHAPstdmac>>&.
+
+
+.section "The &*.arg*& directive"
+This directive may appear only within the body of a macro. It must be followed
+by a single number, optionally preceded by a minus sign. If the number is
+positive (no minus sign), subsequent lines, up to a &*.endarg*& directive, are
+skipped unless the macro has been called with at least that number of
+arguments and the given argument is not an empty string. If the number is
+negative (minus sign present), subsequent lines are skipped if the macro has
+been called with fewer than that number of arguments, or with an empty string 
+for the given argument. For example:
+.code
+ .macro example
+ .arg 2
+ Use these lines if there are at least 2 arguments 
+ and the second one is not empty. Normally there would 
+ be a reference to the 2nd argument. 
+ .endarg
+ .arg -2 
+ Use this line unless there are at least 2 arguments 
+ and the second one is not empty. 
+ .endarg 
+ .endmacro
+.endd
+
+
+.section "The &*.eacharg*& directive"
+This directive may appear only within the body of a macro. It may optionally be
+followed by a single number; if omitted the value is taken to be 1. Subsequent
+lines, up to a &*.endeach*& directive, are processed multiple times, once for
+each remaining argument. Unlike &*.arg*&, an argument that is an empty string 
+is not treated specially.
+
+The number given with &*.eacharg*& defines which argument to start with. While
+these lines are being processed, the remaining macro arguments can be
+referenced relative to the current argument. &`$+1`& refers to the current
+argument, &`$+2`& to the next argument, and so on.
+
+The &*.endeach*& directive may also be followed by a number, again defaulting
+to 1. When &*.endeach*& is reached, the current argument number is incremented
+by that number. If there are still unused arguments available, the lines
+between &*.eacharg*& and &*.endeach*& are processed again.
+
+This example is taken from the coding for the standard &*.row*& macro, which
+generates an &`<entry>`& element for each of its arguments:
+.code
+ .eacharg
+ &<entry>&$+1&</entry>&
+ .endeach
+.endd
+This example is taken from the coding for the standard &*.itable*& macro, which
+processes arguments in pairs to define the table's columns, starting from the
+fifth argument:
+.code
+ .eacharg 5
+ &<colspec colwidth="$+1" align="$+2"/>&
+ .endeach 2
+.endd
+
+
+.section "The &*.echo*& directive"
+This directive takes a single string argument. It writes it to the standard
+error stream. Within a macro, argument substitution takes place, but no other
+processing is done on the string. This directive can be useful for debugging
+macros or writing comments to the user.
+
+
+.section "The &*.endarg*& directive"
+See the description of &*.arg*& above.
+
+
+.section "The &*.endeach*& directive"
+See the description of &*.eacharg*& above.
+
+
+.section "The &*.flag*& directive"
+This directive is used to define flag sequences. The directive must be followed
+either by a standalone flag sequence and one string in quotes, or by a flag
+pair and two strings in quotes. White space separates these items. For example:
+.code
+ .flag && "&amp;"
+ .flag &" "&  "<quote>"  "</quote>"
+.endd
+There are more examples in the definitions of the standard flags. If you
+redefine an existing flag, the new definition overrides the old. There is no
+way to revert to the previous definition.
+
+
+.section "The &*.include*& directive"
+This directive must be followed by a single string argument that is the path to
+a file. The contents of the file are read and incorporated into the input at
+this point. If the string does not contain any slashes, the path to the &X;
+library is prepended. Otherwise, the path is used unaltered.
+
+
+.section "The &*.literal*& directive"
+This must be followed by one of the words &"layout"&, &"text"&, &"off"&, or
+&"xml"&. It forces an end to a previous paragraph, if there is one, and then
+switches between processing modes. The default mode is the &"off"& mode, in
+which text is processed paragraph by paragraph, and flags are recognized.
+Section &<<SECTliteralprocessing>>& describes how input lines are processed in
+the four modes.
+
+
+.section "The &*.macro*& directive" "SECTmacro"
+This directive is used to define macros. It must be followed by a macro name,
+and then, optionally, by any number of arguments. These provide default values.
+The following lines, up to &*.endmacro*&, form the body of the macro. They are
+not processed in any way when the macro is defined; they are processed only
+when the macro is called (see section &<<SECTcallingmacro>>&).
+
+Within the body of a macro, argument substitutions can be specified by means of
+a dollar character and an argument number, for example, &`$3`& for the third
+argument. See also &*.eacharg*& above for the use of &`$+`& to refer to
+relative arguments when looping through them. A reference to an argument that
+is not supplied, and is not given a default, results in an empty substitution.
+
+There is also a facility for a conditional substitution. A reference to an
+argument of the form:
+.display
+&`$=`&&'<digits><delimiter><text><delimiter>'&
+.endd
+inserts the text if the argument is defined and is not an empty string, and
+nothing otherwise. The text is itself scanned for flags and argument
+substitutions. The delimiter must be a single character that does not appear in
+the text. For example:
+.code
+&<chapter$=2+ id="$2"+>&
+.endd
+If this appears in a macro that is called with only one argument, the result
+is:
+.code
+<chapter>
+.endd
+but if the second argument is, say &`abcd`&, the result is:
+.code
+<chapter id="abcd">
+.endd
+This conditional feature can be used with both absolute and relative argument
+references.
+
+If a dollar character is required as data within the body of a macro, it must 
+be doubled. For example:
+.code
+  .macro price
+  The price is $$1.
+  .endmacro
+.endd     
+
+If you redefine an existing macro, the new definition overrides the old. There
+is no way to revert to the previous definition. If you define a macro whose 
+name is the same as the name of a built-in directive you will not be able to 
+call it, because &X; looks for built-in directives before it looks for macros.
+
+It is possible to define a macro within a macro, though clearly care must be 
+taken with argument references to ensure that substitutions happen at the right
+level.
+
+
+
+.section "The &*.pop*& directive"
+&X; keeps a stack of text strings that are manipulated by the &*.push*& and
+&*.pop*& directives. When the end of the input is reached, any strings that
+remain on the stack are popped off, processed for flags, and written to the
+output.
+
+Each string on the stack may, optionally, be associated with an upper case
+letter. If &*.pop*& is followed by an upper case letter, it searches down the
+stack for a string with the same letter. If it cannot find one, it does
+nothing. Otherwise, it pops off, processes, and writes out all the strings down
+to and including the one that matches.
+
+If &*.pop*& is given without a following letter, it pops one string off the
+stack and writes it out. If there is nothing on the stack, an error occurs.
+
+
+.section "The &*.push*& directive"
+This directive pushes a string onto the stack. If the rest of the command line
+starts with an upper case letter followed by white space, that letter is
+associated with the string that is pushed, which consists of the rest of the
+line. For example, the &*.chapter*& macro contains this line:
+.code
+ .push C &</chapter>&
+.endd
+Earlier in the macro there is the line:
+.code
+ .pop C
+.endd
+This arrangement ensures that any previous chapter is terminated before
+starting a new one, and also when the end of the input is reached.
+
+
+.section "The &*.revision*& directive" "SECTrevision"
+This directive is provided to make it easy to set the &`revisionflag`&
+attribute on XML elements in a given portion of the document. The DocBook
+specification states that the &`revisionflag`& attribute is common to all
+elements.
+
+The &*.revision*& directive must be followed by one of the words &"changed"&,
+&"added"&, &"deleted"&, or &"off"&. For any value other than &"off"&, it causes
+the internal variable &'xfpt.rev'& to be set to &`revisionflag=`& followed by
+the given argument. If the argument is &"off"&, the internal variable is
+emptied.
+
+The contents of &'xfpt.rev'& are included in every &`<para>`& element that &X;
+generates. In addition, a number of the standard macros contain references to
+&'xfpt.rev'& in appropriate places. Thus, setting:
+.code
+ .revision changed
+.endd
+should cause all subsequent text to be marked up with &`revisionflag`&
+attributes, until
+.code
+ .revision off
+.endd
+is encountered. Unfortunately, at the time of writing, not all DocBook
+processing software pays attention to the &`revisionflag`& attribute. 
+Furthermore, some software grumbles that it is &"unexpected"& on some elements, 
+though it does still seem to process it correctly.
+
+For handling the most common case (setting and unsetting &"changed"&), the
+standard macros &*.new*& and &*.wen*& are provided (see section
+&<<SECTrevmacs>>&).
+
+
+.section "The &*.set*& directive"
+This directive must be followed by a name and a text string. It defines a user
+variable and gives it a name. A reference to the name in the style of an XML
+entity causes the string to be substituted, without further processing. For
+example:
+.code
+ .set version 4.99
+.endd
+This could be referenced as &`&&version;`&. If a variable is given the name of
+an XML entity, you will not be able to refer to the XML entity, because local
+variables take precedence. There is no way to delete a local variable after it
+has been defined.
+
+

+.chapter "The standard macros for DocBook" "CHAPstdmac" "Standard macros"
+A set of simple macros for commonly needed DocBook features is provided in
+&X;'s library. This may be extended as experience with &X; accumulates. The
+standard macros assume that the standard flags are defined, so a document that
+is going to use these features should start with:
+.code
+ .include stdflags
+ .include stdmacs
+.endd
+All the standard macros except &*new*&, &*index*&, and &*url*& are intended to
+be called as directive lines. Their names are therefore shown with a leading
+dot in the discussion below.
+
+.section "Overall setup"
+There are two macros that should be used only once, at the start of the
+document. The &*.docbook*& macro has no arguments. It inserts into the output
+file the standard header material for a DocBook XML file, which is:
+.code
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
+"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">
+.endd
+The &*.book*& macro has no arguments. It generates &`<book>`& and pushes
+&`</book>`& onto the stack so that it will be output at the end.
+
+
+.section "Chapters, sections, and subsections"
+Chapters, sections, and subsections are supported by three macros that all
+operate in the same way. They are &*.chapter*&, &*.section*&, and
+&*.subsection*&. They take either one, two, or three arguments. The first
+argument is the title. If a second argument is present, and is not an empty
+string, it is set as an ID, and can be used in cross-references. For example:
+.code
+ .chapter "Introduction"
+.endd
+sets no ID, but
+.code
+ .section "A section title" "SECTdemo"
+.endd
+can be referenced from elsewhere in the document by a phrase such as:
+.code
+ see section &<<SECTdemo>>&
+.endd
+When the title of a chapter of section is being used as a running head or foot 
+(for example), it may be too long to fit comfortably into the available space. 
+DocBook provides the facility for a title abbreviation to be specified to deal
+with this problem. If a third argument is given to one of these macros, it
+causes a &`<titleabbrev>`& element to be generated. In this case, a second
+argument must also be provided, but if you do not need an ID, the second
+argument can be an empty string. For example:
+.code
+  .chapter "This chapter has quite a long title" "" "Long title"
+.endd   
+Where and when the abbreviation is used in place of the full title is
+controlled by the stylesheet when the XML is processed.
+
+These three macros use the stack to ensure that each chapter, section, and
+subsection is terminated at the correct point. For example, starting a new
+section automatically terminates an open subsection and a previous section.
+
+
+
+.section "URL references"
+The &*url*& macro generates URL references, and is intended to be called inline
+within the text that is being processed. It generates a &`<ulink>`& element,
+and has either one or two arguments. The first argument is the URL, and the
+second is the text that describes it. For example:
+.code
+ More details are &url(http://x.example, here).
+.endd
+This generates the following XML:
+.code
+ More details are <ulink url="http://x.example">here</ulink>.
+.endd
+If the second argument is absent, the contents of the first argument are used
+instead. If &*url*& is called as a directive, there will be a newline in the 
+output after &`</ulink>`&, which in most cases (such as the example above), you 
+do not want.
+
+
+
+.section "Itemized lists"
+The &*.ilist*& macro marks the start of an itemized list, the items of which
+are normally rendered with bullets or similar markings. The macro can
+optionally be called with one argument, for which there is no default. If the
+argument is present, it is used to add a &`mark=`& attribute to the
+&`<itemizedlist>`& element that is generated. The mark names that can be used
+depend on the software that processes the resulting XML. For HTML output,
+&"square"& and &"opencircle"& work in some browsers.
+
+The text for the first item follows the macro call. The start of the next item
+is indicated by the &*.next*& macro, and the end of the list by &*.endlist*&.
+For example:
+.code
+ .ilist
+ This is the first item.
+ .next
+ This is the next item.
+ .endlist
+.endd
+There may be more than one paragraph in an item. 
+
+
+.section "Ordered lists"
+The &*.olist*& macro marks the start of an ordered list, the items of which are
+numbered. If no argument is given, arabic numerals are used. One of the
+following words can be given as the macro's argument to specify the numeration:
+.display
+&`arabic     `&   arabic numerals
+&`loweralpha `&   lower case letters
+&`lowerroman `&   lower case roman numerals
+&`upperalpha `&   upper case letters
+&`upperroman `&   upper case roman numerals
+.endd
+The text for the first item follows the macro call. The start of the next item
+is indicated by the &*.next*& macro, and the end of the list by &*.endlist*&.
+For example:
+.code
+ .olist lowerroman
+ This is the first item.
+ .next
+ This is the next item.
+ .endlist
+.endd
+There may be more than one paragraph in an item.
+
+
+.section "Variable lists"
+A variable list is one in which each entry is composed of a set of one or more
+terms and an associated description. Typically, the terms are printed in a
+style that makes them stand out, and the description is indented underneath.
+The start of a variable list is indicated by the &*.vlist*& macro, which has
+one optional argument. If present, it defines a title for the list.
+
+Each entry is defined by a &*.vitem*& macro, whose arguments are the terms.
+This is followed by the body of the entry. The list is terminated by the
+&*.endlist*& macro. For example:
+.code
+ .vlist "Font filename extensions"
+ .vitem "TTF"
+ TrueType fonts.
+ .vitem "PFA" "PFB"
+ PostScript fonts.
+ .endlist
+.endd
+As for the other lists, there may be more than one paragraph in an item.
+
+
+.section "Nested lists"
+Lists may be nested as required. Some DocBook processors automatically choose
+different bullets for nested itemized lists, but others do not. The
+&*.endlist*& macro has no useful arguments. Any text that follows it is
+treated as a comment. This can provide an annotation facility that may make the
+input easier to understand when lists are nested.
+
+
+.section "Displayed text"
+In displayed text each non-directive input line generates one output line. The
+&`<literallayout>`& DocBook element is used to achieve this. Two kinds of
+displayed text are supported by the standard macros. They differ in their
+handling of the text itself.
+
+The macro &*.display*& is followed by lines that are processed in the same way
+as normal paragraphs: flags are interpreted, and so there may be font changes
+and so on. The lines are processed in literal layout mode. For example:
+.code
+ .display
+ &`-o`&   set output destination
+ &`-S`&   set library path
+ .endd
+.endd
+The output is as follows:
+.display
+ &`-o`&   set output destination
+ &`-S`&   set library path
+.endd
+
+The macro &*.code*& is followed lines that are not processed in any way, except
+to turn ampersands and angle brackets into XML entities. The lines are
+processed in literal text mode. In addition, &`class="monospaced"`& is added to
+the &`<literallayout>`& element, so that the lines are displayed in a
+monospaced font. For example:
+.code
+ .code
+ z = sqrt(x*x + y*y);
+ .endd
+.endd
+
+As the examples illustrate, both kinds of display are terminated by the
+&*.endd*& macro.
+
+
+
+.section "Block quotes"
+The macro pair &*.blockquote*& and &*.endblockquote*& are used to wrap the
+lines between them in a &`<blockquote>`& element.
+
+
+.section "Revision markings" "SECTrevmacs"
+Two macros are provided to simplify setting and unsetting the &"changed"&
+revision marking (see section &<<SECTrevision>>&). When the revised text is
+substantial (for example, a complete paragraph, table, display, or section), it
+can be placed between &*.new*& and &*.wen*&, as in this example:
+.code
+  This paragraph is not flagged as changed.
+  .new
+  This is a changed paragraph that contains a display:
+  .display
+  whatever
+  .endd
+  This is the next paragraph.
+  .wen      
+  Here is the next, unmarked, paragraph.
+.endd
+When called like this, without an argument, &*.new*& terminates the current
+paragraph, and &*.wen*& always does so. Therefore, even though there are no
+blank lines before &*.new*& or &*.wen*& above, the revised text will end up in
+a paragraph of its own. (You can, of course, put in blank lines if you wish.)
+
+If want to indicate that just a few words inside a paragraph are revised, you
+can call the &*new*& macro with an argument. The macro can be called either as
+a directive or inline:
+.code
+  This is a paragraph that has 
+  .new "a few marked words" 
+  within it. Here are &new(some more) marked words.
+.endd
+The effect of this is to generate a &`<phrase>`& XML element with the
+&`revisionflag`& attribute set. The &*.wen*& macro is not used in this case.
+
+
+.section "Informal tables"
+The &*.itable*& macro starts an informal (untitled) table with some basic
+parameterization. If you are working on a large document that has many tables
+with the same parameters, the best approach is to define your own table macros,
+possibly calling the standard one with specific arguments.
+
+The &*.itable*& macro has four basic arguments:
+.olist
+The frame requirement for the table, which may be one of the words &"all"&,
+&"bottom"&, &"none"& (the default), &"sides"&, &"top"&, or &"topbot"&.
+.next
+The &"colsep"& value for the table. The default is &"0"&, meaning no vertical
+separator lines between columns. The value &"1"& requests vertical separator
+lines.
+.next
+The &"rowsep"& value for the table. The default is &"0"&, meaning no horizontal
+lines between rows. The value &"1"& requests horizontal separator lines.
+.next
+The number of columns.
+.endlist
+These arguments must be followed by two arguments for each column. The first
+specifies the column width, and the second its aligmnent. A column width can be
+specified as an absolute dimension such as 36pt or 2in, or as a proportional
+measure, which has the form of a number followed by an asterisk. The two forms
+can be mixed &-- see the DocBook specification for details.
+
+Straightforward column alignments can be specified as &"center"&, &"left"&, or
+&"right"&. DocBook also has some other possibilities, but sadly they do not 
+seem to include &"centre"&.
+
+Each row of the table is specified using a &*.row*& macro; the entries in
+the row are the macros's arguments. The table is terminated by &*.endtable*&,
+which has no arguments. For example:
+
+.code
+ .itable all 1 1 2 1in left 2in center
+ .row "cell 11" "cell 12"
+ .row "cell 21" "cell 22"
+ .endtable
+.endd
+
+This specifies a framed table, with both column and row separator lines. There
+are two columns: the first is one inch wide and left aligned, and the second is
+two inches wide and centred. There are two rows. The output looks like this:
+
+.itable all 1 1 2 1in left 2in center
+.row "cell 11" "cell 12"
+.row "cell 21" "cell 22"
+.endtable
+
+The &*.row*& macro does not set the &`revisionflag`& attribute in the 
+&`<entry>`& elements that it generates because this appears to be ignored by 
+all current XML processors. However, you can use an inline call of the &*new*& 
+macro within an entry to generate a &`<phrase>`& element with &`revisionflag`& 
+set.
+
+
+.section "Indexes"
+The &*.index*& macro generates &`<indexterm>`& elements (index entries) in the
+output. It takes one or two arguments. The first is the text for the primary
+index term, and the second, if present, specifies a secondary index term. This
+macro can be called either from a directive line, or inline. However, it is
+mostly called as a directive, at the start of a relevant paragraph. For
+example:
+.code
+ .index goose "wild chase"
+ The chasing of wild geese...
+.endd
+
+The &*.makeindex*& macro should be called at the end of the document, at the
+point where you want an index to be generated. It can have up to two
+arguments. The first is the title for the index, for which the default is
+&"Index"&. The second, if present, causes a &`role=`& attribute to be added to
+the &`<index>`& element that is generated. For this to be useful, you need to
+generate &`<indexterm>`& elements that have similar &`role=`& attributes. The
+standard &*index*& macro cannot do this. If you want to generate multiple
+indexes using this mechanism, it is best to define your own macros for each
+index type. For example:
+.code
+ .macro cindex
+ &<indexterm role="concept">&
+ &<primary>&$1&</primary>&
+ .arg 2
+ &<secondary>&$2&</secondary>&
+ .endarg
+ &</indexterm>&
+ .endmacro
+.endd
+This defines a &*.cindex*& macro for the &"concept"& index. At the end of the 
+document you might have:
+.code
+ .makeindex "Concept index" "concept"
+ .makeindex
+.endd
+As long as the processing software can handle multiple indexes, this causes two
+indexes to be generated. The first is entitled &"Concept index"&, and contains 
+only those index entries that were generated by the &*.cindex*& macro. The 
+second contains all index entries.
+
+
+
