Git

Here's a good crash course for subversion users. GitHub provides pretty reasonable git hosting services; open source projects eat free.

Configuration

Dump your user configuration with git config -l:

[recombinator](129) $ git config -l
user.name=Nick Black
user.email=dank@qemfd.net
color.diff=auto
color.status=auto
color.branch=auto
[recombinator](0) $

Dump the system configuration, if one exists, via git config --system -l.
