BugCommunicator is completely rewritten

[Yoshinori K. Okuji]

I have rewritten BugCommunicator from scratch, because I felt that it
was really stupid to invent a new protocol, just for proxy. Also, I
really wanted to avoid mixing C with Ruby, because code shareing was
quite difficult.

Now BugCommunicator is written in pure Ruby. It uses dRuby for
communication between a client and a server. It uses configuration
files written in Ruby. I think the startup cost of the CGI client can
be reduced by mod_ruby significantly, so I don't care about the
performance issue very seriously.

The most important problem is that the source code is ugly, because I
have written the new version for one day. I'll fix that ASAP.

BTW, I've written an official page for BugCommunicator, as I thought
it would better to have a small page than to have nothing. The URL is
<http://www.freesoftware.fsf.org/pupa/bugcomm.html>. Send comments to
me, if any.

Thanks,
Okuji
