develop it, she simply downloaded it. The other dumpers in xemacs seem to be GPL, and I think that the "portable undump" mentioned by another poster is a placeholder for a project that isn't written yet: http://www.xemacs.org/Architecting-XEmacs/unexec.html)

I'm pretty sure that the "Architecting-XEmacs" page is out of date, and the "portable undump" is a reality. Grab current xemacs sources and try doing "./configure --with-pdump"
