-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                          59 Temple Place, Suite 330, Boston, MA 02111 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
-
-	Appendix: 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) 19yy  <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., 59 Temple Place - Suite 330, Boston, MA 02111-1307, 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) 19yy 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
-  Ty Coon, President of Vice
-
-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.

-Basic Installation
-==================
-
-These are installation instructions for Readline-4.3.
-
-The simplest way to compile readline is:
-
-  1. `cd' to the directory containing the readline source code and type
-     `./configure' to configure readline 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 some time.  While running, it prints some
-     messages telling which features it is checking for.
-
-  2. Type `make' to compile readline and build the static readline
-     and history libraries.  If supported, the shared readline and history
-     libraries will be built also.  See below for instructions on compiling
-     the other parts of the distribution.  Typing `make everything' will
-     cause the static and shared libraries (if supported) and the example
-     programs to be built.
-
-  3. Type `make install' to install the static readline and history
-     libraries, the readline include files, the documentation, and, if
-     supported, the shared readline and history libraries.
-
-  4. You can remove the created libraries and object files from the
-     build directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile readline for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the readline developers, and should be used with care.
-
-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 the build directory,
-and Makefiles in the `doc', `shlib', and `examples'
-subdirectories.  It also creates a `config.h' file 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 readline, please try
-to figure out how `configure' could check whether to do them, and
-mail diffs or instructions to <bug-readline@gnu.org> 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 readline `configure.in' requires autoconf
-version 2.50 or newer. 
-
-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 readline 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 readline for one architecture at a
-time in the source code directory.  After you have installed
-readline for one architecture, use `make distclean' before
-reconfiguring for another architecture. 
-
-Installation Names
-==================
-
-By default, `make install' will install the readline libraries in
-`/usr/local/lib', the include files in
-`/usr/local/include/readline', the man pages in `/usr/local/man',
-and the info files in `/usr/local/info'.  You can specify an
-installation prefix other than `/usr/local' by giving `configure'
-the option `--prefix=PATH' or by supplying a value for the
-DESTDIR variable when running `make install'. 
-
-You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. 
-If you give `configure' the option `--exec-prefix=PATH', the
-readline Makefiles will use PATH as the prefix for installing the
-libraries.  Documentation and other data files will still use the
-regular prefix. 
-
-Specifying the System Type
-==========================
-
-There may be some features `configure' can not figure out
-automatically, but need to determine by the type of host readline
-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 (e.g., i386-unknown-freebsd4.2). 
-
-See the file `config.sub' for the possible values of each field.
-
-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: the readline `configure' looks for a site script, but not
-all `configure' scripts do.
-
-Operation Controls
-==================
-
-`configure' recognizes the following options to control how it
-operates.
-

-

-`-q'
-     Do not print messages saying which checks are being made.
-
-`--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.
-
-Optional Features
-=================
-
-The readline `configure' recognizes a single `--with-PACKAGE' option:
-
-`--with-curses'
-    This tells readline that it can find the termcap library functions
-    (tgetent, et al.) in the curses library, rather than a separate
-    termcap library.  Readline uses the termcap functions, but does not
-    link with the termcap or curses library itself, allowing applications
-    which link with readline the to choose an appropriate library.
-    This option tells readline to link the example programs with the
-    curses library rather than libtermcap.
-
-`configure' also recognizes two `--enable-FEATURE' options:
-
-`--enable-shared'
-    Build the shared libraries by default on supported platforms.  The
-    default is `yes'.
-
-`--enable-static'
-    Build the static libraries by default.  The default is `yes'.
- 
-Shared Libraries
-================
-
-There is support for building shared versions of the readline and
-history libraries.  The configure script creates a Makefile in
-the `shlib' subdirectory, and typing `make shared' will cause
-shared versions of the readline and history libraries to be built
-on supported platforms.
-
-If `configure' is given the `--enable-shared' option, it will attempt
-to build the shared libraries by default on supported platforms.
-
-Configure calls the script support/shobj-conf to test whether or
-not shared library creation is supported and to generate the values
-of variables that are substituted into shlib/Makefile.  If you
-try to build shared libraries on an unsupported platform, `make'
-will display a message asking you to update support/shobj-conf for
-your platform.
-
-If you need to update support/shobj-conf, you will need to create
-a `stanza' for your operating system and compiler.  The script uses
-the value of host_os and ${CC} as determined by configure.  For
-instance, FreeBSD 4.2 with any version of gcc is identified as
-`freebsd4.2-gcc*'.
-
-In the stanza for your operating system-compiler pair, you will need to
-define several variables.  They are:
-
-SHOBJ_CC	The C compiler used to compile source files into shareable
-		object files.  This is normally set to the value of ${CC}
-		by configure, and should not need to be changed.
-
-SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
-		position-independent code.  If you are using gcc, this
-		should probably be set to `-fpic'.
-
-SHOBJ_LD	The link editor to be used to create the shared library from
-		the object files created by $SHOBJ_CC.  If you are using
-		gcc, a value of `gcc' will probably work.
-
-SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
-		If you are using gcc, `-shared' may be all that is necessary.
-		These should be the flags needed for generic shared object
-		creation.
-
-SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
-		creation.  Many systems use the -R option to the link
-		editor to embed a path within the library for run-time
-		library searches.  A reasonable value for such systems would
-		be `-R$(libdir)'.
-
-SHLIB_LIBS	Any additional libraries that shared libraries should be
-		linked against when they are created.
-
-SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
-		generating the filename of the shared library.  Many systems
-		use `so'; HP-UX uses `sl'.
-
-SHLIB_LIBVERSION The string to append to the filename to indicate the version
-		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
-		and possibly include version information that allows the
-		run-time loader to load the version of the shared library
-		appropriate for a particular program.  Systems using shared
-		libraries similar to SunOS 4.x use major and minor library
-		version numbers; for those systems a value of
-		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
-		Systems based on System V Release 4 don't use minor version
-		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
-		Other Unix versions use different schemes.
-
-SHLIB_STATUS	Set this to `supported' when you have defined the other
-		necessary variables.  Make uses this to determine whether
-		or not shared library creation should be attempted.  If
-		shared libraries are not supported, this will be set to
-		`unsupported'.
-
-You should look at the existing stanzas in support/shobj-conf for ideas.
-
-Once you have updated support/shobj-conf, re-run configure and type
-`make shared' or `make'.  The shared libraries will be created in the
-shlib subdirectory.
-
-If shared libraries are created, `make install' will install them. 
-You may install only the shared libraries by running `make
-install-shared' from the top-level build directory.  Running `make
-install' in the shlib subdirectory will also work.  If you don't want
-to install any created shared libraries, run `make install-static'.

-Introduction
-============
-
-This is the Gnu Readline library, version 4.3.
-
-The Readline library provides a set of functions for use by applications
-that allow users to edit command lines as they are typed in.  Both
-Emacs and vi editing modes are available.  The Readline library includes
-additional functions to maintain a list of previously-entered command
-lines, to recall and perhaps reedit those lines, and perform csh-like
-history expansion on previous commands.
-
-The history facilites are also placed into a separate library, the
-History library, as part of the build process.  The History library
-may be used without Readline in applications which desire its
-capabilities.
-
-The Readline library is free software, distributed under the terms of
-the [GNU] General Public License, version 2.  For more information, see
-the file COPYING.
-
-To build the library, try typing `./configure', then `make'.  The
-configuration process is automated, so no further intervention should
-be necessary.  Readline builds with `gcc' by default if it is
-available.  If you want to use `cc' instead, type
-
-        CC=cc ./configure
-
-if you are using a Bourne-style shell.  If you are not, the following
-may work:
-
-        env CC=cc ./configure
-
-Read the file INSTALL in this directory for more information about how
-to customize and control the build process.
-
-The file rlconf.h contains C preprocessor defines that enable and disable
-certain Readline features.
-
-The special make target `everything' will build the static and shared
-libraries (if the target platform supports them) and the examples.
-
-Examples
-========
-
-There are several example programs that use Readline features in the
-examples directory.  The `rl' program is of particular interest.  It
-is a command-line interface to Readline, suitable for use in shell
-scripts in place of `read'.
-
-Shared Libraries
-================
-
-There is skeletal support for building shared versions of the
-Readline and History libraries.  The configure script creates
-a Makefile in the `shlib' subdirectory, and typing `make shared'
-will cause shared versions of the Readline and History libraries
-to be built on supported platforms.
-
-If `configure' is given the `--enable-shared' option, it will attempt
-to build the shared libraries by default on supported platforms.
-
-Configure calls the script support/shobj-conf to test whether or
-not shared library creation is supported and to generate the values
-of variables that are substituted into shlib/Makefile.  If you
-try to build shared libraries on an unsupported platform, `make'
-will display a message asking you to update support/shobj-conf for
-your platform.
-
-If you need to update support/shobj-conf, you will need to create
-a `stanza' for your operating system and compiler.  The script uses
-the value of host_os and ${CC} as determined by configure.  For
-instance, FreeBSD 4.2 with any version of gcc is identified as
-`freebsd4.2-gcc*'.
-
-In the stanza for your operating system-compiler pair, you will need to
-define several variables.  They are:
-
-SHOBJ_CC	The C compiler used to compile source files into shareable
-		object files.  This is normally set to the value of ${CC}
-		by configure, and should not need to be changed.
-
-SHOBJ_CFLAGS	Flags to pass to the C compiler ($SHOBJ_CC) to create
-		position-independent code.  If you are using gcc, this
-		should probably be set to `-fpic'.
-
-SHOBJ_LD	The link editor to be used to create the shared library from
-		the object files created by $SHOBJ_CC.  If you are using
-		gcc, a value of `gcc' will probably work.
-
-SHOBJ_LDFLAGS	Flags to pass to SHOBJ_LD to enable shared object creation.
-		If you are using gcc, `-shared' may be all that is necessary.
-		These should be the flags needed for generic shared object
-		creation.
-
-SHLIB_XLDFLAGS	Additional flags to pass to SHOBJ_LD for shared library
-		creation.  Many systems use the -R option to the link
-		editor to embed a path within the library for run-time
-		library searches.  A reasonable value for such systems would
-		be `-R$(libdir)'.
-
-SHLIB_LIBS	Any additional libraries that shared libraries should be
-		linked against when they are created.
-
-SHLIB_LIBSUFF	The suffix to add to `libreadline' and `libhistory' when
-		generating the filename of the shared library.  Many systems
-		use `so'; HP-UX uses `sl'.
-
-SHLIB_LIBVERSION The string to append to the filename to indicate the version
-		of the shared library.  It should begin with $(SHLIB_LIBSUFF),
-		and possibly include version information that allows the
-		run-time loader to load the version of the shared library
-		appropriate for a particular program.  Systems using shared
-		libraries similar to SunOS 4.x use major and minor library
-		version numbers; for those systems a value of
-		`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
-		Systems based on System V Release 4 don't use minor version
-		numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
-		Other Unix versions use different schemes.
-
-SHLIB_STATUS	Set this to `supported' when you have defined the other
-		necessary variables.  Make uses this to determine whether
-		or not shared library creation should be attempted.
-
-You should look at the existing stanzas in support/shobj-conf for ideas.
-
-Once you have updated support/shobj-conf, re-run configure and type
-`make shared'.  The shared libraries will be created in the shlib
-subdirectory.
-
-If shared libraries are created, `make install' will install them. 
-You may install only the shared libraries by running `make
-install-shared' from the top-level build directory.  Running `make
-install' in the shlib subdirectory will also work.  If you don't want
-to install any created shared libraries, run `make install-static'. 
-
-Documentation
-=============
-
-The documentation for the Readline and History libraries appears in
-the `doc' subdirectory.  There are three texinfo files and a
-Unix-style manual page describing the facilities available in the
-Readline library.  The texinfo files include both user and
-programmer's manuals.  HTML versions of the manuals appear in the
-`doc' subdirectory as well. 
-
-Reporting Bugs
-==============
-
-Bug reports for Readline should be sent to:
-
-        bug-readline@gnu.org
-
-When reporting a bug, please include the following information:
-
-        * the version number and release status of Readline (e.g., 4.2-release)
-        * the machine and OS that it is running on
-        * a list of the compilation flags or the contents of `config.h', if
-          appropriate
-        * a description of the bug
-        * a recipe for recreating the bug reliably
-        * a fix for the bug if you have one!
-
-If you would like to contact the Readline maintainer directly, send mail
-to bash-maintainers@gnu.org.
-
-Since Readline is developed along with bash, the bug-bash@gnu.org mailing
-list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
-Readline bug reports and fixes.
