+Compat.el is a forwards-compatibility library for (GNU) Emacs Lisp,
+versions 24.3 and newer.
+
+The intended audience of this library aren't day-to-day users, but
+package developers that wish to make use of newer functionality, not
+provided in older versions of Emacs, without breaking compatibility
+for users bound to specific Emacs releases.
+
+Version 24.3 is chosen as the oldest version, because this is the
+newest version on CentOS 7. It is intended to preserve compatibility
+for at least as the Centos 7 reaches EOL, 2024.
+
+Note that compat.el provides a few prefixed function, ie. functions
+with a compat- prefix. These are used to provide extended
+functionality for commands that are already defined (sort, assoc,
+...). It might be possible to transform these into advised functions
+later on, so that the modified functionality is accessible without a
+prefix. Feedback on this point is appreciated.
