July 4, 2015 Thank you for downloading and installing this setup kit for XEmacs 21.5. This kit is based on the current XEmacs Mercurial repository, found at https://hg@bitbucket.org. Please see http://www.xemacs.org/Develop/hgaccess.html for more (unfortunately out-of-date) information about the XEmacs 21.5 Mercurial repositories. XEmacs-21.5 is software under development. Please do not use this software unless you are prepared to experience and report bugs. The 21.4 releases of XEmacs are more stable and are better suited to the less adventurous in the user population. See http://www.xemacs.org/Releases/index.html#Beta for guidelines. This setup kit now includes all the XEmacs packages. By default, this setup kit installs the following recommended packages: mule-base, latin-euro-standards, latin-unity, locale, lookup, c-support, cc-mode, debug, dired, ecb, edebug, ediff, edit-utils, efs, eieio, fsf-compat, mail-lib, net-utils, os-utils, pc, perl-modes, prog-modes, semantic, sh-script, sounds-wav, speedbar, texinfo, text-modes, time, xemacs-base, and xemacs-devel. Unless you are very familiar with the XEmacs package system, I suggest that you not de-select any of the recommended packages, but rather augment the list of packages to be installed. This setup kit can be installed along with a 21.4 installation. By default each setup kit will install to C:\Program Files\XEmacs\XEmacs-VERSION (where VERSION is either 21.4* or 21.5*) and all the installed versions will share packages. One significant difference between the two kits is that the 21.5 kit supports MULE. Refer to http://www.xemacs.org/Documentation/21.5/html/xemacs-faq.html#SEC65 for more details on MULE. This kit now gives the user a chance to delete the EMACSPACKAGEPATH key, which is no longer necessary and will cause XEmacs not to find its installed packages at runtime. This kit was built with Inno Setup, see http://www.jrsoftware.org/isinfo.php for details on Inno Setup. Regards, Vin Shelton
