Re: One possible bug-tracking system.

    What about GNATS?

    I have no experience at all with GNATS but when I read the
    introduction at <http://www.gnu.org/software/gnats/> it seems to fit
    most of the needs and wishes expressed here.

I think it does.  Also, it is a GNU package, which is an argument
in favor.

Another possibility is to use RT, which is what the GNU Project uses
for many other things.  I think it can be used via email.  I don't
know whether RT is suitable for bug tracking, though.
