Tools for scala developers.  I have a lot more but it is going to take

me some time to organize everything.

Usage:

    source /path/to/libscala.sh   # add to your .profile or similar

    ./git-java/install.sh         # run this one time

If you're lucky, that's it.  Examples of available things:

    gh-commit  # accepts sha-1 or rev, shows in browser.  Tab-completion on svn revs!

    java -XX:           # tab-completion on java -XX: options (a tad verbose at the moment)

    scala -J-XX:        # also completes on -J-XX: options

    gco            # a git checkout which completes on local branches only

    gh-find Global      # open a browser to those files in trunk matching Global

The git-java part enables you to check jars and *.class files into a

git repository and see a useful diff.  After you run ./git-java/install.sh,

it will tell you to run git-java/demo.sh.  Do so.  You should see this:

```diff
