-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-            59 Temple Place - Suite 330, Boston, MA  02111-1307, 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.

-  string is made up of pairs "<oldchar>=<newchar>" which are separated
-  by a colon. Oldchar and newchar are either single ascii characters, 
-  or the two character sequence ^x, where x is an ascii character, or
-  a 3 digit octal value prepended with '\'. the string "\040=.:^M=q"
-  rebinds '.' to set marks, and the return rey will abort copy mode.
-

-Thousand enhancements: help resizible, copy'n'paste in main
-  socket loop, and no more '\0' hackin'. :WS=\E8;%d;%dt:
-
-screen can now resize windows under sunview.
-
-^A : set crlf on|off
-  effects markroutine join.
-
-screen learned about sized windows under X
-
-screen -ls (-d) -q
-  quiet option. We count the number of detached (attached) sessions and set
-  a return value of 10+n. The -q option inhibits all startup
-  warnings/messages. i.e. screen -R -q may return with code 12 or higher
-  or start a new/old session.
-
-pow_detach_msg "text string"
-  new command, allows messages, terminal reset, etc. on logout caused
-  by pow_detach.
-
-^A : learned a new keyword "set":
-  commands like "login on" , "vbell off", ... affect the default for
-  windows to be created. But commands like "set login off" affect
-  the actual setting of this window. and not the default.
-  such commands may be bound to keys. example: 
-  bind 'O' set login off
-  is valid in your .screenrc as well as typed at the ':' prompt.
-  a bonus is ":set all" which is synonym to ":help".
-  At the Colon prompt also KeyNames can be entered, alothough that makes
-  not always sense.
-
-^A x uses a builtin lockprg, if 
-  a) we don't find our lockprg, or
-  b) user supplies us with the environmet variable LOCKPRG set to "builtin"
-  the builtin locks until your login password is typed. on systems using
-  "shadow password files" you are prompted for a password.
-
-markroutine can append joined.
-
-screen removes the "controlling tty" from utmp while ptys are attached.
-
-markroutine performs CR+NL when '\n' is pressed
-
-screen may die quietly, when no TERMCAP entry for "screen" is
-found, and screen is run under X-windows
-
-_SEQUENT_ marks sequent386_ptx
-
-screen runs now under SunOS4.1.1 (we need setsid()!).
-
-bug in SetForeWindow fixed.
-
-rare markroutine bug fixed.
-
-we dont open every file the attacher tells us.
-
-we have now our wonderful "Wuff, Wuff" visual_bell
-
-we have now the interprocess-communication-buffer. secure version.
-
-'^A =' removes the interprocess-communication-buffer.
-
-markroutine as in 2.1
-
-markroutine: 'a' toggles append mode,
-             '>' like ' ', but immediately WriteFile(DUMP_EXCHANGE) then.
-             'A' like ' ', but first switch to append mode.
-
-.screenrc understands "screen 2:faui09 rlogin faui09 -l jnweiger"
-                  and "password none"
-                  and "vbell [on|off]"
-
-'^A :' allows .screenrc commands "online".
-
-screen now receives new $TERM from attacher, when it is reattached 
-
-MakeClientSocket() fifo version does now test for access.
-
-.screenrc learns "hardstatus {on|off}"
-
-termcap's VB is used for vbell if available.
-
-Attach() code rewritten:
-	screen now lists socket directory, if it does not find a suitable socket
-	screen -d [host.tty] detaches a running screen. 
-
-screen -[ls|list]
-	list all sockets that we find in our sockdir
-
-when the socket has been removed, send a SIGCHLD to the poor SCREEN 
-process and it will try to recover. then try a 'screen -r' again.
-all the socket stuff lives now in an extra file.
-
-Major changes in version 2.4:
-=============================
-
-*  Test version that presents the erlangen extensions from 2.0 in a 2.3
-   screen.
-
-*  window resize support
-
-*  screen locking C-a x
-
-*  support for SYSV
-
-*  password protection
-
-*  copy & paste across screens
-
-*  remote detach and power detach
-
-Major changes in version 2.3:
-
-*  Terminal emulation has been significantly enhanced and bugfixed.
-
-*  We now fully update the last character on the screen for true auto-
-   margin terminals, though there may be some delay before the character
-   can be safely added to the screen.  If your terminal has character
-   insert it will be used to shorten the delay.
-
-*  Added the "termcap" .screenrc command to tweak your terminal's termcap
-   entry AND to customize the termcap generated for the virtual terminals.
-   See also the -L and -O command-line options, and the SCREENCAP environ-
-   ment variable.
-
-*  Fixed screen's character handling when detached or suspended to NOT block
-   the child processes in their windows -- output continues to be processed
-   in the background.
-
-*  Added a.k.a.s (window-name aliases) that allow you to customize the
-   window-information line, including being able to change the name on-
-   the-fly to reflect what's currently running in the window (see the
-   -k option, shellaka command, and ALSO KNOWN AS discussion in the doc).
-
-*  Added the ability to log the output of a window to a file (see the
-   "C-a H" (log) command).
-
-*  Flow-control can now be set for each window and switched interactively
-   (see the "flow" command, -f option, and FLOW CONTROL discussion).
-
-*  Individual windows can be included or excluded from mention in the
-   /etc/utmp file (see the "login" command and -l option).
-
-*  Added an activity monitor, which allows you to have a window watched for
-   the start of any output and alert you when it occurs (see the "C-a M"
-   (monitor) command).
-
-*  Enhanced the information in the window-information line to keep track of
-   windows that have: logging turned on '(L)'; beeped in the background '!';
-   became active while being monitored '@' (see the "C-a w" (windows) command).
-
-*  Added an on-line help display that lists all the commands and their
-   key bindings (see the "C-a ?" (help) command).
-
-*  Extended handling of the beep message (and also the new activity message)
-   to allow '~' to specify a literal beep (see the "beep" and "activity"
-   .screenrc commands).
-
-*  You can now set the default action on receipt of a hangup signal:  detach
-   or terminate (see the "autodetach" .screenrc command).
-
-*  Routing of characters to their virtual terminals has been enhanced to
-   not drop characters nor (in rare circumstances) hang up screen.
-
-*  The NFS compatibility has been enhanced.
-
-Major changes in version 2.0a:
-
-*  Screen allows you to `detach' the "screen" session from the physical
-   terminal and resume it at a later point in time (possibly on a
-   different terminal or in a different login session).
-
-  To get an impression of this functionality do the following:
-
-     - call "screen" and create a couple of windows
-     - type Control-A Control-D (screen terminates; you are back
-       in the shell)
-     - call "screen -r" to resume the detached screen
-
-*  Screen supports multiple character sets and the ISO 2022 control
-   functions to designate and switch between character sets.
-   This allows you, for instance, to make use of the VT100 graphics
-   character set or national character sets.

-   screen: frequently asked questions -- known problems -- unimplemented bugs
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
-
-
-Q:   Why is it  impossible to download  a file with Kermit/sz/rz  when  
-     screen is running? Do I need to set some special variables?
- 
-A:   Screen  always   interprets   control-sequences   sent   by   the
-     applications   and  translates/optimizes  them  for  the  current
-     terminal type.  Screen always  parses  the  user  input  for  its
-     escape  character  (CTRL-A).   Both are basic screen features and
-     cannot be switched off.  Even  if  it  were  possible  to  switch
-     screen into a completely transparent mode, you could never switch
-     between windows, while kermit/sz/rz is downloading  a  file.  You  
-     must  wait til  the end as  kermit/sz/rz will  not transmit  your 
-     input during  a file transfer and as kermit/sz/rz would  be  very  
-     confused  if  screen switched  away  the  window  containing  the
-     other  kermit/sz/rz.  Simply detach your screen session  for each 
-     file transfer and start the  transfer program only from the shell 
-     where you started screen. 
-
-Q:   I  am using screen with  a  YYY terminal, which supports  the XXX
-     graphic language.  I  am very happy with  it, except one thing: I 
-     cannot render graphics into screen windows.
-  
-A:   You are out of luck there. Screen provides  a fixed set of escape
-     sequences in order to make  it possible to switch terminal types.
-     Screen has  to know exactly what the escape sequences  do  to the
-     terminal because  it  must hold  an  image  in  memory. Otherwise 
-     screen could  not  restore  the  image  if  you switch to another 
-     window.  Because  of  this  you  have  to  change screens  escape
-     sequence parser (ansi.c)  to  pass the XXX graphics sequences  to 
-     the terminal.  Of course the graphics will  be lost if you switch
-     to  another window. Screen  will only  honour graphics  sequences 
-     that are demanded by an overwhelming majority.
-
-Q:   For some unknown reason, the  fifo  in  /tmp/screens/S-myname  is
-     gone,  and  i  can't  resume my screen session. Is there a way to
-     recreate the fifo?
- 
-A:   Screen checks the fifo/socket  whenever  it  receives  a  SIGCHLD
-     signal.  If missing, the fifo/socket is recreated then. If screen
-     is  running  non  set-uid  the  user  can  issue  a  'kill  -CHLD
-     screenpid'  directly (it is -CHILD on some systems). Screenpid is
-     the process-id of the screen process found in a 'ps -x'  listing.
-     But  usually  this won't work, as screen should be installed set-
-     uid root. In this case you will not be able to send it a  signal,
-     but  the  kernel  will.  It  does  so, whenever a child of screen
-     changes its state. Find the process-id (shellpid  below)  of  the
-     "least  important"  shell  running  inside  screen. The try 'kill
-     -STOP shellpid'.  If the fifo/socket does not  reappear,  destroy
-     the  shell  process.  You  sacrify one shell to save the rest. If
-     nothing works, please do  not  forget  to  remove  all  processes
-     running in the lost screen session.
-
-Q:   When you start "screen" a page of text comes up to  start  you
-     off.   Is  there  a way to get rid of this text as a command line
-     argument or by using a switch of some sort.  
-  
-A:   Just  put  the following line in your ~/.screenrc:
-         startup_message off
-     Many peole ask this, although  it  is  in the man page, too :-)
-
-Q:   Start "screen emacs"  and  run   emacs   function   suspend-emacs
-     (ctrl-z). The window containing emacs vanishes. 
- 
-A:   This is a known  bug.  Unfortunatly  there   is   no   easy   fix
-     because  this  is specified in the POSIX  standard.  When  a  new
-     window is created Screen opens  up  a  new  session  because  the
-     window    has    to  get   the  pty  as a controlling terminal (a
-     session  can  only  have  one  controlling  terminal).  With  the
-     setsid()   call the   process also    creates   a   new   process
-     group.  This process  group is orphaned,   because  there  is  no
-     process  in   the  session    which is  not   in   the    process
-     group.   Now if the process group  leader  (i.e.  your   program)
-     gets   a  TTIN/TTOU/TSTP,   POSIX  states that  the  kernel  must
-     send   a   KILL signal to the process group because there is   no
-     one  left  to  continue  the process.  Even    if   screen  would
-     try to restart the program, that would be after it  received  the
-     KILL signal which  cannot  be caught  or ignored.
-     
-     tromey@klab.caltech.edu (Tom Tromey):  I've  noticed  this  exact
-     same problem.  I put this in my .emacs file.  It seems to work:
-        
-	;; If running under screen, disable C-z.
-	(if (and (getenv "STY") (not window-system))
-		(global-unset-key "\C-z"))
-
-Q:   Screen gets the terminal size wrong and messes up.
- 
-A:   Before you start screen: Check with 'stty -a' what  the  terminal
-     driver  thinks  about  rows  and  columns.  Check the environment
-     variables LINES and COLUMNS.  Then from within screen check  with
-     the info command (CTRL-A i) what size screen thinks your terminal
-     is. If correcting tty driver setting  and  environment  variables
-     does  not help, look up the terminal capability definition. First
-     the TERMCAP environment variable. If this is not set, look up the
-     terminals  name  as  defined  in the environment variable TERM in
-     /etc/termcap or in the terminfo database with untic  or  infocmp.
-     There  may  be  :li=...:  and  :co=...:  or even :ll=...: entries
-     (cols#... and lines#...  when it's terminfo) defined incorrectly.
-     Either  construct  your  own  TERMCAP  environment variables with
-     correct settings, use screens terminfo/termcap  command  in  your
-     .screenrc  file  or  have  the  database  corrected by the system
-     administrator.
-
-Q:   Screen messes up the terminal output when I use my favourite  ap-
-     plication. Setting the terminal size does not help.
- 
-A:   Probably you got the termcap/terminfo entries wrong. Fixing  this
-     is  a  three  stage  procedure.  First,  find  out if terminfo or
-     termcap is  used.  If  your   system   only   has   /etc/termcap,
-     but    not  /usr/lib/terminfo/...   then  you  are using termcap.
-     Easy. But if your system has both, then it depends how the appli-
-     cation and how  screen  were  linked.  Beware,  if  your applica-
-     tion runs on another host via rlogin, telnet  or  the  like,  you
-     should check the terminfo/termcap  databases there. If you cannot
-     tell if terminfo or termcap is used (or  you  just  want  to   be
-     save),   the   do   all  steps  in  stage  3 in parallel for both
-     systems (on all envolved hosts).  Second:  Understand  the  basic
-     rules  how  screen  does its terminal  emulation.  When screen is
-     started or reattached, it relies on the TERM environment variable
-     to  correctly  reflect  the  terminal type  you  have  physically
-     in front of you. And the entry should either exist in the  system
-     terminfo/termcap  database  or  be  specified via the TERMCAP en-
-     vironment variable (if screen is using the  termcap  system).  On
-     the  other  end,  screen understands one set of control codes. It
-     relies on the application using these codes. This means  applica-
-     tions   that  run  under screen  must be able to adapt their con-
-     trol codes to screen. The application should use the  TERM  vari-
-     able  and  termcap or  terminfo  library to find out how to drive
-     its terminal. When running under screen, the terminal is  virtual
-     and  is  only defined by  the  set  of  control codes that screen
-     understands.  The  TERM  variable  is  automatically    set    to
-     "screen"  and  the  "screen"-entries  should  exist  in the data-
-     bases. If your application uses hardcoded  control  codes  rather
-     than  a database, you are  on  your own.  Hint:  The codes under-
-     stood by screen are a superset  of  the  very  common  definition
-     named  "vt100".  Look  at   the   documentation  of  screen.  The
-     codes  are  listed there. Third:  Have  the  entry  "screen"  in-
-     stalled  on  all hosts or make sure you  can  live  with "vt100".
-     Check the codes sent by your application, when the TERM  variable
-     is  set  to "screen". Do not try to set the TERM  variable inside
-     screen  to anything other than "screen"  or "vt100"  or  compati-
-     ble.  Thus your application can drive screen correctly. Also take
-     care that  a good entry is installed  for your physical  terminal
-     that   screen   has  to drive.  Even if the entry was good enough
-     for your application to drive the terminal  directly, screen  may
-     find   flaws,   as  it tries to use other capabilities while  op-
-     timizing   the   screen   output.    The    screenrc     commands
-     "termcap"  and/or  "terminfo"  may help to fine-tune capabilities
-     without calling the supervisor to change the database.
-
-Q:   I cannot configure screen. Sed does not work.
- 
-A:   The  regular expressions used  in  our  configure scrip  are  too
-     complicated for GNU sed version 2.03.  In  this regard it is  bug
-     compatible with  Ultrix 3.1 "sed":  GNU  sed  version 2.03  dumps
-     core with our configure script.  Try an older release.  E.g. from
-     ftp.uni-erlangen.de:/pub/utilities/screen/sed-2.02b.tar.gz
-
-Q:   When reattaching a session  from  a  different  Workstation,  the
-     DISPLAY   environment  variable  should be updated. Even ``CTLR-A
-     : setenv DISPLAY newhost:0'' does not work as expected.
- 
-A:   Under unix every process  has its own environment.  The  environ-
-     ment  of the SCREEN process can be changed with the `setenv' com-
-     mand.  This  however  cannot  affect the   environment   of   the
-     shells or applications already running under screen. Subsequently
-     spawned processes will reflect the changes.  One should be  aware
-     of  this  problem when running applications from very old shells.
-     Screen is a means for keeping processes alive.
-
-Q:   About once every 5 times  I ran the program,  rather than getting
-     a "screen," I got someone elses IRC output/input.
- 
-A:   What probably happened is that an IRC process was left running on
-     a pseudo tty  in such a way that the  kernel thought  the tty was
-     available  for reallocation.   You  can  fix  this  behaviour  by
-     applying the SunOS 4.1.x tty jumbo patch (100513-04).
- 
-Q:   Screen compiled on SunOS 5.3 cannot reattach a detached session.
- 
-A:   You are  using /usr/ucb/cc, this compiler  is wrong.  Actually it 
-     links  with  a  C-library that  mis-interprets dirent.  Try again
-     with /opt/SUNWspro/bin/cc!
-
-Q:   The "talk" command does not work when Screen is active.
- 
-A:   Talk  and several  other programs  rely on entries  in the  Utmp-
-     Database  (/etc/utmp).  On some  systems this  Database is  world 
-     writable,  on others  it is not.  If it  is not,  screen must  be 
-     installed with the appropriate  permissions (user or group s-bit)
-     just like any  program that uses  PTYs (rlogin, xterm, ...). When
-     screen cannot write to utmp, you will see messages on you display
-     which do not belong to any screen window. 
-     When screen can update utmp, it is not guaranteed that it does as
-     you  expect.  First this depends  on  the config.h  file defining 
-     UTMPOK, LOGINDEFAULT, and perhaps CAREFULUTMP.  Second it depends
-     on the screenrc files (system wide and per user), if utmp entries
-     are done.  Third, you can control  whether windows are logged  in
-     with screens ``login'' command.
-
-Q:   Seteuid()  does not work as expected in AIX.  Attempting a multi-
-     user-attach results in a screen-panic: "seteuid: not owner".
- 
-A:   This   is  not  a   screen  problem.   According  to  Kay  Nettle
-     (pkn@cs.utexas.edu) you need the AIX patch PTF 423674.
-
-Q:   When  I  type  cd directory (any directory  or just  blank)  from 
-     within one of the windows in screen, the whole thing just freezes
-     up.
- 
-A:   You display the  current working directory  in xterm's title bar,
-     This may be caused by hardcoded ESC-sequences in the shell prompt
-     or in an cd alias.  In Xterm the coding is 
-     		ESC ] n ; string_to_display ^G 
-     where n = 1, 2, 3  selects the location of the  displayed string.
-     Screen misinterprets  this as the ansi  operating system  comment
-     sequence:
-     		ESC ] osc_string 
-     and waits (according to ansi) for the string terminator
-     		ESC \
-     Screen versions after 3.5.12 may provide a workaround.
-
-Q:   Mesg or biff cannot be turned on or off while running screen.
- 
-A:   Screen failed to change the owner of the pty it uses. You need to
-     install screen setuid-root. See the file INSTALL for details.
-
-Q:   The cursor left key deletes the characters instead of just moving the
-     cursor. A redisplay (^Al) brings everything back.
-
-A:   Your terminal emulator treats the backspace as "destructive". You
-     can probably change this somewhere in the setup. We can't think
-     of a reason why anybody would want a destructive backspace, but
-     if you really must have it, add the lines
-	termcap  <TERM> 'bc@:bs@'
-	terminfo <TERM> 'bc@:bs@'
-     to your ~/.screenrc (replace <TERM> with the terminal type your
-     emulator uses).
-
-Q:   I have an old SysV OS (like Motorola SysV68) and sometimes screen
-     doesn't reset the attributes correctly. A redisplay (^Al) doesn't
-     make things better.
-
-A:   The libcurses library has a bug if attributes are cleared with
-     the special ue/se capabilities. As a workaround (other than upgrading
-     your system) modify 'rmul' (and 'rmso'?) in screen's terminfo entry:
-	rmul=\E[m, rmso=\E[m

-Installation of screen3.6                                         jw 9.04.95
-
-
-0.) This instruction is quite lengthy
--------------------------------------
-.. and there are still important items near the end. Start here:
-Unpack. Screen comes as a compressed tar archive. You need gzip to 
-uncompress.  And... well, you probably already managed that step, 
-when you are reading this.
-
-For general documentation on the coding and usage standards this
-distributions follows, see the GNU standards document on
-prep.ai.mit.edu:pub/gnu/standards.*, especially the `Makefile
-Conventions', `Configuration', and `User Interfaces' sections.
-
-
-1.) configure & config.status
------------------------------
-Run configure. This should create a reasonable Makefile and a config.h file
-suited for your machine. Rename config.status to reflect the architecture 
-(hostname) where it was built. To reconfigure quickly for that architecture
-just run that config.status file.
-If this process fails, try to find out what configure did do and what it
-should have checked. Mail me.
-Actually the initial Makefile that comes with the distribution just runs
-configure -- thus you can start by typing 'make' right after unpacking.
-You will be prompted to run 'make' again, which will really make screen.
-
-2.) Makefile & config.h
------------------------
-Look through the Makefile & user configuration section in config.h and check
-pathnames. Change them to suit your installation requirements. Usually 
-sysadmins discuss the location of SOCKDIR, whether it should be in /tmp or 
-not. At least it must be on a filesystem that supports sockets/fifos.
-SOCKDIR must not point into an AFS (Andrew File System) mounted directory. 
-If you are uncertain about your NFS implementation, use a UFS directory for 
-SOCKDIR. Personally, I favour a users home directory and recommend the the 
-/tmp/ area. 
-The path for ETCSCREENRC may also need to be adapted.
-
-3.) how to actually compile 
----------------------------
-Run 'make'. Screen should compile without too many warnings :)
-The creation of term.h, comm.h, tty.c or osdef.h may fail on some machines
-for some odd reason. (E.g. the sed under SCO-unix is known to be 
-case-insensitive and breaks term.h.) If so, please mail a short description 
-of the problem to screen@uni-erlangen.de and use the files ending in .dist 
-as a replacement (or in case of osdef.h retry with an empty file).
-You can then try 'make install' (if you dare).
-
-4.) where to install
---------------------
-You may well run screen from your private binary directory and with a 
-private socket directory like $HOME/.screen. But to have a full featured
-screen and (from a users point of view) more secure pty's you should
-consult a system administrator and discuss installing screen setuid-root
-in some globally accessible directory like /usr/local/bin.
-
-Consider this, when deciding whether you install screen setuid-root:
-- On some machines root privileges are required to open pty's. 
-- Pty's should be owned by the user, so that she can do chmod to prevent
-  intruder attacks. The PTYs used by screen will remain world read-writable
-  if screen is not installed setuid-root.
-- Some commands only work properly when the pty is owned by the user.
-  These include mesg and biff.
-- The ^At feature may need to lseek and read the kernel file to retrieve 
-  the load average. 
-- On most machines utmp slots can only be created/manipulated with root
-  privileges. Users will appear to be logged on the primary terminal
-  instead of the screen windows, if screen is not installed setuid-root.
-- Multi-user screen sessions are only allowed when screen has a root-s-bit.
-- If screen sockets of multiple users are kept in one directory (e.g. 
-  /tmp/screens), this directory must be world writable when screen is not
-  installed setuid-root. Any user can remove or abuse any socket then.
-  
-
-5.) doc/screen.1 & doc/screen.texinfo
--------------------------------------
-The man page doc/screen.1 should go to /usr/local/man/man1, or some similar
-directory. It should format nicely with nroff -man. If it does not, then
-try removing extra dots with: sed -e 's/^\.\././' < screen.1 | nroff -man 
-The info page doc/screen.texinfo contains basically the same information as
-the man-page, we may have missed one or another thing in one of the files.
-If so, mail me.
-
-6.) etc/screenrc & etc/etcscreenrc
-----------------------------------
-The files screenrc and etc/etcscreenrc are instructive samples that
-demonstrate what can/should be done from your private .screenrc and from
-$ETCSCREENRC -- do not just copy them. Read them.  Look through the 
-etcscreenrc file for system wide defaults that you like to set. e.g. 
-autodetach off, startup_message off, vbell on, ...
-Since version 3.2.15 the screenrc file syntax changed slightly. All rc files
-from previous versions should be run through the 'newsyntax' script that comes 
-with this package.
-If and only if you want to install screen as a console multiplexer, look
-at the *.sample files and what 'make cscreen' suggests.
-
-7.) terminfo/screeninfo.src & terminfo/screencap
-------------------------------------------------
-Every now and then we update the termcap/terminfo entries for screen. 
-E.g. keycodes were added in 3.6.0 -- thus you check that your termcap/terminfo
-database is up to date. See the README in the terminfo subdirectory.
-
-8.) have fun
-------------
-To get an idea what the basic screen commands are, read the file README.
-Request snail mail address for liquid and solid donations. :-)

-                  ----------------------------
-                   What's new in screen-3.5 ?
-                  ----------------------------
-
-
-* Texinfo manpage! Thanks to Jason Merrill.
-
-* Screen now has a very large 'configure' script. If you have
-  problems with the resulting configuration please send mail to
-  screen@uni-erlangen.de.
-
-* Stackable overlay planes.
-  All commands are available even if you work with an overlay. Thus
-  you can be in copy/paste mode on several windows!
-
-* Unification of key bindings and screen commands. All keys now generate
-  commands.
-
-* Screen now reads/writes only in asyncronous mode.
-
-* Ansi parser speedup code resulting in much faster output of text.
-
-* Changed the rc file syntax. Commands now directly affect the current
-  window. The default settings are changed with 'def...' commands.
-  The 'set' keyword no longer exists.
-  Please run the 'newsyntax' script on your old screenrc files!
-
-* Emacs style isearch added to copy mode. Try ^A ESC ^R screen ^R ^R
-  to locate the last three occurences of the word 'screen' in the
-  history buffer.
-
-* New command 'silence'. Alarms the user whenever there was inactivity
-  for a specified amount of time on a certain window.
-  Useful if you want to wait for a compilation to end.
-
-* Much better margin handling:
-  Screen now handles autowrapped lines correctly in the redisplay and
-  copy/paste functions.
-
-* New commands for pastebuffer management:
-  'copy_reg' copies the pastebuffer to a register,
-  'ins_reg' pastes a register,
-  'register' fills a register with a string,
-  'process' stuffs a register into strings input queue.
-
-* Autonuke feature. Flush the output buffer if the window gets
-  cleared. Enable this with 'autonuke on'.
-
-* Modifications to save memory: Empty attribute and font lines don't
-  get allocated. This is very useful if you have a lage scrollback.
-
-* Multi display support:
-  You can now attach from more than one terminal to a session with
-  the '-x' option.
-
-* New option '-S' to specify socket name.
-
-* Experimental multiuser support added:
-  You can start screen in multiuser Mode by prepending the socket
-  name with a '/' (or by the command 'multiuser on').
-  If another user wants to attach to the screen session, he can do
-  this by prepending the socketname with 'screenuser/'.
-  Of course he must be in the access control list for a successful
-  attach (see the acladd/acldel command).
-  
-* Extension to the 'screen' command: You can now specify tty lines
-  instead of programs. This can be used for console management.
-  Added the command 'break' to send a break to the tty line.
-  Not really a new feature, but terminal initialisation  now works
-  on suns.
-
-* Input/output filters added. This has been implemented to allow the
-  user to configure an open tty line, but got soon exended to allow
-  all sorts of filters. For more information read the explanation
-  of the 'exec' command in the man page and check the 'fdpat.ps'
-  document.
-
-* Screen can now be started detached (screen -d -m -S sockname).
-  This is usefull if you want to start screen in your /etc/rc file
-  (e.g. as a console multiplexer)
-
-* Console grabbing added ('console on' command). 
-
-* Windows can now be selected by akas, too. (Per default bound to the
-  >'< key.)
-
-* New terminal capabiliteise CS/CE for cursorkey control.
-
-* setenv/unsetenv commands added.
-
-* Expansion of environment variables ($VAR) and terminal capabilities
-  ($:TC:) in the screenrc files and detach messages.
-  Example: pow_detach_msg "Session of \$LOGNAME \$:cr:\$:nl:ended."
-   
-* New commands:
-  'hardcopydir' and 'logdir' to change the output directories,
-  'partial' and 'allpartial' to make screen only refresh the line
-  containing the cursor if a window is selected (useful for slow
-  modem connections).
-
-* Cleanup of the provided termcap/terminfo file. Please install
-  the new one!
-
-* The program 'terminfo/checktc.c' does a visual check of a
-  termcap/terminfo entry. Please try it before calling screen and
-  in a screen session.
-
-* LOTS of bugfixes and code cleanup.
-
-Thanks to all the beta testers who helped porting screen to at least
-the following platforms: Ultrix, SunOS, Solaris, BSD43, linux, NEWSOS,
-Irix, OSF/1, Harris CX/UX, hpux, dynix/ptx, AIX.
-And even more thanks to the brave who attempted to use the 'exec'
-command features.
-
-    Donnate patches, bugreports, suggestions, money, beer & pizza to
-            screen@uni-erlangen.de

-                  ----------------------------
-                   What's new in screen-3.6 ?
-                  ----------------------------
-
-* Input translation! This makes the vt100 emulation complete.
-  As an addition it is now possible to bind any command to any
-  (function-) key. See the man page for more details (bindkey
-  command).
-
-* Status line support. Each window can have a different status line. 
-  Use the ANSI APC string to set the status line, i.e.:
-  <ESC>_<status string><ESC>\
-  (For convenience the xterm sequence is also accepted.)
-  You may want to add
-    termcap  * '' ':hs:ts=\E_:fs=\E\\:ds=\E_\E\\:'
-    terminfo * '' ':hs:ts=\E_:fs=\E\\:ds=\E_\E\\:'
-  to your ~/.screenrc to make screen advertise the hardstatus
-  support.
-  
-* Zombie feature added. Windows now may generate a message (with a
-  timestamp) if they die and stay around until the user presses
-  a key.
-
-* New paste syntax: Paste can now concatenate registers and paste
-  either on screen or in anouther register.
-  This makes the old "ins_reg", "copy_reg" commands obsolete.
-
-* More architecures supported. Screen now runs on AIX3.2.5,
-  Solaris, NeXT and some other exotic platforms.
-
-* Kanji support added. Screen understands JIS, EUC and SJIS coding.
-  This is an experimental feature.
-
-* GR charset switching (ISO 2022) implemented. Can be enabled with
-  the "gr" command.
-
-* C1 sequences implemented (see the "c1" command).
-
-* Tek support from Xiaoguang Zhang. Apply tek.patch if you want to
-  make screen pass tek sequences.
-
-* List of new commands:
-    bindkey, c1, command, defc1, defgr, defkanji, gr, kanji, mapdefault,
-    mapnotnext, maptimeout, pastefont, printcmd, readreg, stuff, zombie
-
-* Lots of other bugs fixed.

-                  ----------------------------
-                   What's new in screen-3.7 ?
-                  ----------------------------
-
-* Color support. Screen understands the following capabilities:
-      AF (setaf) = Set foreground color (ANSI compatible)
-      AB (setab) = Set background color (ANSI compatible)
-      AX         = Does understand ANSI set default fg/bg color
-                   (\E[39m / \E[49m)
-    The tweaks for the color xterm would be:
-      termcap  xterm 'AF=\E[3%dm:AB=\E[4%dm'
-      terminfo xterm 'AF=\E[3%p1%dm:AB=\E[4%p1%dm'
-
-* New 'digraph' command (bound to ^A^V)
-  ^A^Va" or ^A^V0344 input an a-umlaut
-
-* activity/bell message strings can now include the window title:
-    %t - title
-    %n - number (a single % still works)
-
-* 'defhstatus' command to give everey window a default
-  hardstatus line. ^E is used as a string escape instead of %
-  (see above). Try 'defhstatus "Screen: window ^E (^Et)"'
-
-* Input parser changed to understand '^' (see ^E above).
-
-Note that the linux color xterm has a stupid bug: the characters
-get the color of the cursor, therefore if you change color and move
-the cursor around all the characters will get the new color...
-Here is a patch:
-    pub/utilities/screen/color_xterm_patch
-Btw.: rxvt works fine.
-
-* Optional Braille support. If you can read Braille and have one of
-  the devices listed in README.DOTSCREEN, please compile with
-  -DHAVE_BRAILLE and let us know if this feature is useful.

-
-                  ----------------------------
-                   What's new in screen-3.9 ?
-                  ----------------------------
-
-* real multiuser support
-    A window can now be displayed on more than one attached displays.
-    Screen does all the necessary clipping if the window size doesn't
-    fit the display.
-    New command:
-      ^AF - fit the window size into the display size.
-
-* split screen support
-    A display may now host multiple windows.
-    New commands:
-      ^AS - split horizontally. This add another region to the display
-      ^A<Tab> - move the focus to the next region
-      ^AX - kill the current region
-      ^AQ - kill all other regions
-
-* hardstatus emulation support
-    The last line of the display may now be used as a hardstatus
-    line if the terminal doesn't have the 'hs' capability.
-    New commands:
-      hardstatus [always]lastline
-      hardstatus [always]message
-      hardstatus [always]ignore
-
-* configurable window seperator and hardstatus strings
-    The window (region) seperator and the hardstatus can be set to an
-    arbitrary string containing screen's % escape sequences.
-    The window's hardstatus is just another escape sequence, '%h'.
-    New commands:
-      hardstatus string [string]
-      caption string [string]
-    The default strings are "%h" (hardstatus) and "%3n %t" (caption).
-
-* permanent window seperator
-    The window seperator can be set to stay on screen even if
-    the display contains only one region
-    New commands:
-      caption always
-      caption splitonly
-
-* many new escapes
-    %c - current time HH:MM (*CHANGE*: this was %w in screen-3.7)
-    %C - current time HH:MM in 24h format
-    %l - the load of the system
-    %h - hardstatus of the window
-    %w - all window names
-    %W - all window names except the current window
-    %u - all other users on this window
-    %? - the part to the next %? is displayed only if an escape
-         expands to an nonempty string.
-    %: - "else" part of %?
-    Some escapes like %c may be qualified with a '0' (like %0c)
-    to make screen use '0' instead of space as a filler.
-    Others understand a length qualifier, like %3n.
-    If escapes like the current time are used as hardstatus/caption
-    string screen will update them so that you can always have
-    the current time onscreen.
-    *CHANGE* ~ is no longer used as bell character, use ^G instead!
-
-* logfile timestamps and flush timeout
-    New commands:
-      logfile flush <secs>
-      logtstamp [on|off]
-      logtstamp string [string]
-      logtstamp after [secs]
-
-* configurable breaktype
-    You can now choose one of TIOCSBRK, TCSBRK, tcsendbreak.
-    New commands:
-      breaktype
-      defbreaktype
-
-* other new commands:
-    hstatus - set the window's hardstatus
-    defslowpaste
-    defsilence
-
-* optional builtin telnet.
-    This is useful if screen is used as frontend to a terminal
-    multiplexor. Use //telnet to access the builtin telnet program,
-    as in: 'screen //telnet host [port]'
-
-* remote detach and reattach change:
-    '-d' is now ignored if the screen is already detached and you
-    want to reattach. You can also use '-RR' to make screen use
-    the first session found if more than one session is available.
-    Thus '-d -RR' or '-x -RR' always gets you a screen.
-
-* support for history compaction
-    You can tell screen to suppress trailing blank lines when
-    scolling up text into the history buffer. (Wayne Davison)
-    New command:
-      compacthist
-
-* optional Braille support. If you can read Braille and have one of
-    the devices listed in README.DOTSCREEN, please compile with
-    -DHAVE_BRAILLE and let us know if this feature is useful.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR           user executables [EPREFIX/bin]
-  --sbindir=DIR          system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR       program executables [EPREFIX/libexec]
-  --datadir=DIR          read-only architecture-independent data [PREFIX/share]

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have
-              headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

- *                     without further parameters. 2) Evry user has a default
- *                     umask that gives himself all permissions on the windows

- *                     The commad is now executed by the user typing the final

- * 06.02.95 -- 3.05.66 DisplayLine() does now clipping to reduce coredump-
- *                     frequency. Window size is adapted to the display that
- *                     types input, to reduce multi-user confusion. Scrollback
- *                     mode still may get the wrong size.
- * 07.02.95 -- 3.05.67 WinRewrite() also needs to clip. Users without unix
- *                     account, but with screen password allowed. Chacl
- *                     allows password change, su prompts for user name too.

- *                     remaining display. Simple ESC-CR fix in the vt100
- *                     state machine.
- * 26.03.95 -- 3.05.69 Markroutine() needs to resize the window to avoid 
- *                     coredumps, just like WinProcess() already does.
- *                     More NEED_ flags added in comm.c to avoid coredumps.
- * 04.04.95 -- 3.06.02 Simple ESC-CR fix in the vt100 state machine.
- *                     Now compiles again with all extras disabled.
- *                     Zombie resurrect added. defc1, defgr, defkanji

- *                     query. Some missing NEED_XXX added in comm.c.
- *                     Better default tty permissions/group test.
- *                     More AUX support, now compiles with POSIX.
- *                     Function keycodes xtermified (F11, F12).
- *                     Paste bug fixed (only worked with KANJI).
- *                     Check bcopy before memcpy/memmove.
- *                     FindSocket code much fixed & improved.
- * 10.04.95 -- 3.05.70 Display_displays() now shows the users permissions on 
- *                     the currently displayed window, this is easier than a 
- *                     full featured lsacl, but also helps. chacl can now copy
- *                     users, but we need to copy windows.
- * 26.04.95 -- 3.05.71 Multi digit screen numbers in utmp. MakeWindow() now
- *                     echoes what it does, just like RemakeWindow() when
- *                     'verbose on' (default off).
- *                     `screen -ls myname/' will find own(!) non-multi sessions.
- *                     Command line option -q improved and documented.
- *                     'debug off' also shuts attacher debugging off now.

- *                     open(O_NONBLOCK) does not work on 4.1.3, using O_NDELAY.
- *                     There are writes to exp_wid2chan[-1], XXX I just added 
- *                     fillers to the mux structure, please debug this ASAP! 
- *                     WindowByName() prefers exact matches now. Esc forwarding
- *                     from Frontend to Backend suppressed unless specified.
- * 26.06.95 -- 3.05.73 Improving the combination of dflag and rflag: If both
- *                     are set, a screen session is reattached, regardless
- *                     if it was previously detached or attached elseewhere.
- *                     "screen -D -RR" is thus most powerful: Give me my screen
- *                     session here and now. No matter, if this means creating
- *                     a new session (due to the second R without warning 
- *                     message), detching the session first (and due to the
- *                     capitalised D logging out), or simply attaching to it.
- * 13.07.95 -- 3.05.74 Markroutine learned new join mode: comma seperated.
- *                     Can disable the detach feature from config.h.
- *                     Configure.in now calls etc/toolcheck. Password is no
- *                     longer a static array.
- * 30.07.95 -- 3.05.75 Karl Heuer wants to install with a relative symlink.

- * 03.09.95 -- 3.06.04 SetRendition display check. Solaris unblock
- *                     SIGHUP. w_curchar->w_rend, lintified.
- *                     Shadow-password code moved and rewritten
- *                     (includes sun C2).

- *  putenv  --  put value into environment
- *
- *  Usage:  i = putenv (string)
- *    int i;
- *    char  *string;
- *
- *  where string is of the form <name>=<value>.
- *  If "value" is 0, then "name" will be deleted from the environment.
- *  Putenv returns 0 normally, -1 on error (not enough core for malloc).
- *
- *  Putenv may need to add a new name into the environment, or to
- *  associate a value longer than the current value with a particular
- *  name.  So, to make life simpler, putenv() copies your entire
- *  environment into the heap (i.e. malloc()) from the stack
- *  (i.e. where it resides when your process is initiated) the first
- *  time you call it.
- *
- *  HISTORY
- *  3-Sep-91 Michael Schroeder (mlschroe). Modified to behave as
- *    as putenv.
- * 16-Aug-91 Tim MacKenzie (tym) at Monash University. Modified for
- *    use in screen (iScreen) (ignores final int parameter)
- * 14-Oct-85 Michael Mauldin (mlm) at Carnegie-Mellon University
- *      Ripped out of CMU lib for Rob-O-Matic portability
- * 20-Nov-79  Steven Shafer (sas) at Carnegie-Mellon University
- *    Created for VAX.  Too bad Bell Labs didn't provide this.  It's
- *    unfortunate that you have to copy the whole environment onto the
- *    heap, but the bookkeeping-and-not-so-much-copying approach turns
- *    out to be much hairier.  So, I decided to do the simple thing,
- *    copying the entire environment onto the heap the first time you
- *    call putenv(), then doing realloc() uniformly later on.
