Anoncvs and viewcvs enabled for minion

[Roger Dingledine <arma@mit.edu>]

I've updated http://mixminion.net/ to have links to viewcvs, and
instructions for pserver access:

<p>And you can browse the Minion cvs:
<ul>
<li><a href="http://cvs.seul.org/cgi-bin/viewcvs.cgi/?cvsroot=minion";>ViewCVS</a>
<li><a href="cvs/">Regularly updated cvs sandbox</a>
<li>anonymous pserver access (password is guest):
<ul>
<li>cvs -d :pserver:guest@cvs.seul.org:/home/minion/cvsroot login
<li>cvs -d :pserver:guest@cvs.seul.org:/home/minion/cvsroot co src doc
</ul>
</ul>
