[Nix-dev] Re: Is Emacs 22 still needed?

sure, that is true. I guess there is a trade-off involved here. It's
nice to have old versions of popular packages around in Nixpkgs, yet
there seems to be little point in doing that unless someone is actually
using those old versions. Nixpkgs itself does not refer to Emacs 22
anywhere, i.e. our configuration doesn't depend on it at all.

Of course, this doesn't imply that Emacs 22 unused. It's possible that
people have patched/forked/overridden the setup to go back to the old
version for some reason. 

Still, it doesn't seem likely, because Emacs 23 has been out and stable
for quite some time now.

I see no point in keeping it around unless someone actually needs it.
Personally, I'd like to delete the old version to simply our package
database. I don't feel strongly about it, but, still, I felt compelled
to ask.

Take care,
Peter
