This directory tree holds version 22.1 of SXEmacs, the extensible, customizable, self-documenting real-time display editor. See the file `etc/NEWS' for information on new features and other user-visible changes since the last version of SXEmacs. The file `INSTALL' in this directory says how to build SXEmacs. The file `PROBLEMS' contains information on many common problems that occur in building, installing and running SXEmacs. The file 'README.packages' will guide you in the installation of (essential) add on packages. The file `configure' is a shell script to acclimate SXEmacs to the oddities of your processor and operating system. It will create a file named `Makefile' (a script for the `make' program), which helps automate the process of building and installing SXEmacs. See INSTALL for more detailed information. The file `configure.ac' is the input used by the autoconf program to construct the `configure' script. The file `Makefile.in' is a template used by `configure' to create `Makefile'. There are several subdirectories: `ChangeLog.d' -- ChangeLog files for all the SXEmacs versions. `contrib' -- A few scripts and things to make life as a SXEmacs developer a little easier. `etc' -- Tutorials, readme's, icons, developer images. `info' -- SXEmacs documentation in Texinfo format. `lib-src' -- Holds the source code for some utility programs for use by or with SXEmacs, like movemail and etags. `lisp' -- Holds the Emacs Lisp code for SXEmacs. `m4' -- The auxiliary m4 scripts used by the build chain. `modules' -- Source code for the "emodules". `src' -- The rest of the C sources are here. `tests' -- The test suite.
