CVS questions

[Kervin L. Pierre]

Hi,

I'm about to build/configure CVS imapd 2.2 branch for virtual domain 
support with a single IP.  I have a few questions before I start.

What are the CVS branches, tags available for download?  Which do I use 
if I want 2.2 branch? http://asg.web.cmu.edu/cyrus/download/anoncvs.html 
gives a CVS checkout command without a branch tag, is that the 2.2 source?

What sasl do I use for 2.2 imapd?  If CVS, again which branch should I 
checkout?

Thanks,
