No need to fatal () on startup if $PWD doesn't exist; chdir to "/" instead. src/ChangeLog addition: 2009-11-08 Aidan Kehoe <kehoea@parhasard.net> * sysfile.h (DEFAULT_DIRECTORY_FALLBACK): New #define, "/" on Unix and "C:\\" on Win32 native, a directory that should "always" be available. * fileio.c (Fexpand_file_name): Use DEFAULT_DIRECTORY_FALLBACK here, instead of conditionalising on WIN32_NATIVE. * editfns.c (get_home_directory): Use DEFAULT_DIRECTORY_FALLBACK if looking up the home directory fails, on both Windows and Unix. * buffer.c (init_initial_directory): Don't give a fatal error if the current directory doesn't exist, chdir to DEFAULT_DIRECTORY_FALLBACK instead.

This directory contains a number of XEmacs dynamic modules.  These
modules can be loaded directly with the command 'M-x load-module'.
However, the preferred method of loading a module is to issue a
"(require 'module-name)" command to the Lisp interpreter.  This will
store information so that a later "(unload-feature 'module-name)" can
succeed.

To compile one of these modules, simply enter the desired directory,
type 'configure', and then 'make'.  If you are building the module for
an installed XEmacs, then 'make install' will place the module in the
appropriate directory for XEmacs to find it later (assuming you have
permission to write to that directory).  A subsequent 'load-module' or
'require' will then load the module, as described above.

Each of these demonstrates different features and limitations of the
XEmacs module loading technology.  For a complete discussion on XEmacs
dynamic modules, please consult the XEmacs Module Writers Guide, which
can be found in the ../info directory.

For those wanting to get started with module writing, please see the
'sample' directory.  It contains two subdirectories: internal and
external.  The 'internal' subdirectory contains the framework needed to
migrate some core piece of XEmacs functionality into code that can
either be compiled into the core or built as a separate module.  The
'external' subdirectory contains the somewhat simpler framework needed
to build a module separately from XEmacs.  These should be considered
starting places for module writing.
