Emacs 23 doesn't require newer Linuxes, it can be compiled on recent-ish earlier OSes easily enough. Probably more easily than building obsolete versions of XEmacs! I have been using CVS builds of Emacs 23 for several years without many problems. But anyway, I hope Emacs 22 can be supported. - D. -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
