IMPORTANT: Some renamings. Will need to be applied carefully to the carbon repository, in the following order: -- pixel_to_char_size -> pixel_to_frame_unit_size -- char_to_pixel_size -> frame_unit_to_pixel_size -- pixel_to_real_char_size -> pixel_to_char_size -- char_to_real_pixel_size -> char_to_pixel_size -- Reverse second and third arguments of change_frame_size() and change_frame_size_1() to try to make functions consistent in putting width before height. -- Eliminate old round_size_to_char, because it didn't really do anything differently from round_size_to_real_char() -- round_size_to_real_char -> round_size_to_char; any places that called the old round_size_to_char should just call the new one. 2. IMPORTANT FOR CARBON: The set_frame_size() method is now passed sizes in "frame units", like all other frame-sizing functions, rather than some hacked-up combination of char-cell units and total pixel size. This only affects window systems that use "pixelated geometry", and I'm not sure if Carbon is one of them. MS Windows is pixelated, X and GTK are not. For pixelated-geometry systems, the size in set_frame_size() is in displayable pixels rather than total pixels and needs to be converted appropriately; take a look at the changes made to mswindows_set_frame_size() method if necessary. 3. Add a big long comment in frame.c describing how frame geometry works. 4. Remove MS Windows-specific character height and width fields, duplicative and unused. 5. frame-displayable-pixel-* and set-frame-displayable-pixel-* didn't use to work on MS Windows, but they do now. 6. In general, clean up the handling of "pixelated geometry" so that fewer functions have to worry about this. This is really an abomination that should be removed entirely but that will have to happen later. Fix some buggy code in frame_conversion_internal() that happened to "work" because it was countered by oppositely buggy code in change_frame_size(). 7. Clean up some frame-size code in toolbar.c and use functions already provided in frame.c instead of rolling its own. 8. Fix check_frame_size() in window.c, which formerly didn't take pixelated geometry into account.

**** WARNING ****
This file was never meant to be proper documentation, and now is bitrotted.
See the file gnuserv.1 and/or the sources for more information.

****
NOTE: This version of gnuserv has some enhancements over the original version 
  distributed by Andy Norman. See the end of this file for more details. 
****

To install, copy gnuserv.el into a directory on your GNU Emacs
load-path. Edit Makefile and change INCLUDES to point to the src
directory underneath your emacs source tree (or make yourself a
config.h file in this directory by hand, starting with config.h.proto
as a first cut) and type:

     make

This should compile the server and the two clients. Now put gnuserv,
gnuclient and gnudoit in a directory that users have in their executable
search paths.

This version of gnuserv has been enhanced by a number of people, including
Bob Weiner <weiner@mot.com>, Darrell Kindred <dkindred@cmu.edu>,
Arup Mukherjee <arup@cmu.edu>, and Ben Wing <ben@xemacs.org>. The
modifications are basically as follows:

Bob Weiner: 

     Integrated support for several versions of emacs. New requests
     from gnuclient cause the creation of new frames. Removed the
     restriction on the length of the string passed to gnudoit. Later
     added a server-done-function variable to control what happens to
     a buffer after the user is done with it. Mods to each of the .c
     files as well as gnuserv.el.

Darrell Kindred:

     Removed the restriction on the length of the string returned from
     a gnudoit request, for the purposes of unix/internet sockets.
     Allow the gnudoit request to be read from stdin if it's not
     specified on the command line. Internet sockets are not opened
     unless the GNU_SECURE variable is specified. Unix sockets are
     created in a protected ancestral directory, since many Unix
     variants don't enforce socket permissions properly. An internet
     socket accepting local connections is not opened by default
     because this would make it possibly to override all security on
     the unix socket. See the man page for details. Unless told to do
     otherwise by a command-line argument, gnuclient and gnudoit now
     try to open a unix socket by default if support for them was
     compiled in.  Mods to each of the .c files and to gnuserv.el.

Arup Mukherjee:
     Removed the restriction on the length of the string returned from
     a gnudoit request, for the purposes of sysv ipc. Added support
     for the "gnuserv-frame" variable allowing you to specify control
     whether or not new screens are created in response to each
     gnuclient request. Made a number of other bugfixes and changes to
     the lisp part of the code, allowing gnuserv to work properly with
     newer emacs versions. All the changes are listed in the changelog
     at the beginning of gnuserv.el. Also fixed up the man page to
     reflect the new gnuserv features. On HPs, stopped the "-r"
     parameter (in gnuclient) from defaulting to /net/<remotehost>.
     Not all installations want this, and it's much harder to debug
     when things stop working. Changed the man page to reflect this.
     Mods to each of the .c files, gnuserv.el and gnuserv.1

     More recently - added Xauth(1X11)-style authentication to gnuserv (as 
     of version 2.1). Although the code is completely new, credit is
     due to Richard Caley <rjc@cogsci.edinburgh.ac.uk> ... he wrote a
     prototype implementation from which I borrowed the basic
     mechanism for hooking Xauth into gnuserv. 

Ben Wing:
     Added gnuattach.
