-This sort of thing has been done for bunches of functions.  Gnus does
-not redefine any native Emacs functions while running under XEmacs---it
-does this @code{defalias} thing with Gnus equivalents instead.  Cleaner
-all over.
-
-In the cases where the XEmacs function interface was obviously cleaner,
-I used it instead.  For example @code{gnus-region-active-p} is an alias
-for @code{region-active-p} in XEmacs, whereas in Emacs it is a function.
-
-Of course, I could have chosen XEmacs as my native platform and done
-mapping functions the other way around.  But I didn't.  The performance
-hit these indirections impose on Gnus under XEmacs should be slight.
