[hibernate-dev] Hibernate Core is now using Git

[Scott Marlow]

Adding to the favorite git tools:

Command completion support (git-completion.bash) is pretty good if your
a command shell type person.  The script is available via Git project
source and other places (included in Fedora).  If you read the below
mentioned progit book (just ordered my copy last week :), you will have
read http://progit.org/book/ch2-11.html which talks about
git-completion.bash.

There are various GUIs but gitk is my favorite so far.
