The subdirectories of this directory contain source code for the XEmacs
facilities written in Emacs Lisp. *.el files are Elisp source, and *.elc
files are byte-compiled versions of the corresponding *.el files.
Byte-compiled files are architecture-independent.
When XEmacs starts up, it adds all subdirectories of the site-lisp
directory. The site-lisp directory normally exists only in
installation trees. For more information about the site-lisp
directory see the NEWS file.
After XEmacs adds all subdirectories of the site-lisp directory, it
adds all subdirectories of this directory to the load-path (the list
of directories to be searched when loading files.) To speed up this
process, this directory has been rearranged to have very few files at
the top-level, so that emacs doesn't have to stat() several hundred
files to find the dozen or so which are actually subdirectories.
Directories whose names begin with "-" or "." are not added to the default
The only files which remain at top-level are those which you might
reasonably want to alter when installing or customizing XEmacs at your
site. The files which may appear at top level are:
paths.el You may need to change the default pathnames here,
but probably not. This is loaded before XEmacs is
site-init.el To pre-load additional libraries into XEmacs and dump
them in the executable, load them from this file.
site-load.el This is like site-init.el, but if you want the
docstrings of your preloaded libraries to be kept in
the DOC file instead of in the executable, you should
load them from this file instead. To do this, you must
also cause them to be scanned when the DOC file is
generated by editing ../src/Makefile.in.in and
site-start.el This is loaded each time XEmacs starts up, before the
user's .emacs file.
default.el This is loaded each time XEmacs starts up, after the
user's .emacs file, unless .emacs sets the variable
inhibit-default-init to t.
version.el This contains the version information for XEmacs.
These are the main subdirectories:
prim Fundamental XEmacs functionality. Some of this is
pre-dumped with XEmacs, some is autoloaded.
utils Various utility functions that some other XEmacs
packages build on. These are not user commands.
modes Text-editing and programming-language-sensitive modes.
emulators XEmacs can emulate a few different editors. These are
a bit more than what `modes' generally are.
term Terminal-specific customization files. When XEmacs
starts, it checks the $TERM environment variable to
see what type of terminal the user is running on, and
loads a file named $TERM.el from this directory, if
that file exists.
vms VMS-specific code.
x11 X Window System-specific code.
games Various ways to waste time.
packages Random other utilities that are not primarily about
editing text. For example, code for automatically
uncompressing .Z files would be here. This is an
`everything else' sort of directory.
Some packages are fairly large; those have been given their own directories:
bytecomp The XEmacs-lisp compiler.
calendar A calendar and appointment manager.
comint General code for interacting with inferior processes,
like shell buffers and lisp interpreters.
dired The directory editor.
edebug A source-level debugger for Elisp.
ediff A comprehensive visual interface to diff and patch.
electric The "electric" commands; these implement temporary
windows for help, list-buffers, etc.
energize An interface to the Lucid Energize system.
eos An interface to Sun's SparcWorks product.
eterm A merge of the comint shell mode with an
gnus An NNTP-based newsreader; version 3.14.
hm--html-menus Menu interface to html-mode.
hyperbole An information management and hypertext system.
ilisp A comint-based package for interacting with inferior
mh-e An interface to the MH-E mail handling system.
oobr An Object-Oriented class browser.
pcl-cvs An interface to the Concurrent Version System.
rmail A BABYL-format mail reader.
sunpro Additional code for interfacing with SunPro products.
tooltalk An inteface to the ToolTalk communication protocol.
viper A full-featured VI emulator.
vm View Mail, an UNIX-format alternative to RMAIL.
w3 A World Wide Web interface.
