The binary-kits subdirectory
(ftp://ftp.xemacs.org/pub/xemacs/xemacs-20.4/binary-kits/) 
holds executables for XEmacs 20.4.  The binary-kits are in the form:
 
xemacs-$VERSION-$ARCHITECTURE-$VENDOR-$OS-$FEATURE.tar.gz
 
Each kit has an associated README file which contains detailed
installation instructions, as well as information about how the kit
was built and what features it contains.  Please view the README in
it's entirety before downloading a particular kit to insure
compatibility with your system.
 
NOTE: 
To use these binary-kits, you will also need the files in either:

/pub/xemacs/xemacs-20.4/xemacs-20.4-common.tar.gz (for Non-Mule kits) OR
/pub/xemacs/xemacs-20.4/xemacs-20.4-common-mule.tar.gz (for Mule kits)

These are the architecture-independent parts of the installation tree
(the `lisp', `etc', and `info' directories.)  Please see your kit's
README file for more information.
