 ===============================
 
 Find here the source for compat.el, 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.
