Emacs and XEmacs each come with Lisp packages that are lacking in the
other. The two versions have some significant differences at the Lisp
-programming level.
-
-Many XEmacs features have found their way into recent versions of Emacs,
-and more features can be expected in the future, but there are still many
-differences between the two.
-
-The FSF has used some of the code in XEmacs, and would like to use
-other parts, but the earlier XEmacs maintainers did not always keep
-track of the authors of contributed code, which makes it impossible
-for the FSF to get copyright papers signed for that code. (The FSF
-requires these papers for all the code included in Emacs, aside from
-generic C support packages that are not integrated into the code of
-Emacs proper.)
