This directory tree holds version 20.0 of GNU Emacs, the extensible, customizable, self-documenting real-time display editor. You may encounter bugs in this release. If you do, please report them; your bug reports are valuable contributions to the FSF, since they allow us to notice and fix problems on machines we don't have, or in code we don't use often. See the file BUGS for more information on how to report bugs. See the files `etc/NEWS' and `etc/news.texi' for information on new features and other user-visible changes since the last version of Emacs. The file INSTALL in this directory says how to bring up GNU Emacs on Unix, once you have loaded the entire subtree of this directory. The file etc/PROBLEMS contains information on many common problems that occur in building, installing and running Emacs. Reports of bugs in Emacs should be sent to the mailing list email@example.com. See the "Bugs" section of the Emacs manual for more information on how to report bugs. (The file `BUGS' in this directory explains how you can find and read that section using the Info files that come with Emacs.) See `etc/MAILINGLISTS' for more information on mailing lists relating to GNU packages. The `etc' subdirectory contains several other files, named in capital letters, which you should look at when installing GNU Emacs. The file `configure' is a shell script to acclimate Emacs to the oddities of your processor and operating system. It creates the file `Makefile' (a script for the `make' program), which automates the process of building and installing Emacs. See INSTALL for more detailed information. The file `configure.in' is the input used by the autoconf program to construct the `configure' script. Since Emacs has configuration requirements that autoconf can't meet, `configure.in' uses an unholy marriage of custom-baked configuration code and autoconf macros; it may be wise to avoid rebuilding `configure' from `configure.in' when possible. The file `Makefile.in' is a template used by `configure' to create `Makefile'. The file `make-dist' is a shell script to build a distribution tar file from the current Emacs tree, containing only those files appropriate for distribution. If you make extensive changes to Emacs, this script will help you distribute your version to others. There are several subdirectories: `src' holds the C code for Emacs (the Emacs Lisp interpreter and its primitives, the redisplay code, and some basic editing functions). `lisp' holds the Emacs Lisp code for Emacs (most everything else). `lib-src' holds the source code for some utility programs for use by or with Emacs, like movemail and etags. `etc' holds miscellaneous architecture-independent data files Emacs uses, like the tutorial text and the Zippy the Pinhead quote database. The contents of the `lisp', `info' and `man' subdirectories are architecture-independent too. `info' holds the Info documentation tree for Emacs. `man' holds the source code for the Emacs manual. Note that the Emacs Lisp manual sources are distributed separately. (They are twice as large as the Emacs manual in the man subdirectory.) `msdos' holds configuration files for compiling Emacs under MSDOG. `vms' holds instructions and useful files for running Emacs under VMS. `nt' holds various command files and documentation files that pertain to running Emacs on Windows NT.
