Yeah, I'm not very familiar with CVS, and I wasn't sure I had the right
version.  This is what I did to check out the code:

cvs -d:pserver:anonymous at cvs.xfce.sf.net:/cvsroot/xfce login
cvs -d:pserver:anonymous at cvs.xfce.sf.net:/cvsroot/xfce co xfce-devel/xfwm4

(got this from xfwm4-4.0.6 README)

How do I check out the latest code?
