[GAP Forum] GAP mode for emacs

[Attila Egri-Nagy]

Dear Ivan,

I would very much like to test/use your gap-mode, but I see no file
for downloading (without checking out a repository). Also a few lines
on usage would be helpful.

Thanks!
best,
attila

I also haven't tested on Xemacs.  The code can be found at https://bitbucket.org/gvol/gap-mode/ so feel free to open an issue there if you have problems or suggestions (or contact me directly via email).

Running gap in Emacs seems to work for me, though I haven't tested it much.  Thus, if you need that functionality, please don't get rid of your old install!
