Hi Pat,
Here's the good Mercurial tutorial: hginit.com.
Here's what I've been writing up. Possibly confusing.
http://www.cis.upenn.edu/~matuszek/cit594-2011/Pages/mercurial-v2.html
Here's a repository we can play with. Point your browser at
https://bitbucket.org/matuszek/daveandpat
When you get Mercurial installed, notice the lines:
Clone this repository (size: 1.4 KB): HTTPS / SSH
hg clone https://matuszek@bitbucket.org/matuszek/daveandpat
That second line is telling you what to enter at the command line
to get your copy.
Above that, "r0" means it's version 0 in _this_ repository (maybe
not in yours or mine), but "b4da2ed4833f" is a unique ID valid
for everybody.

PS. Hey Donna, this one is public. Wanna play?
