-#######->WARNING<-####### Directory structure changed, see commit message

If you use git-python as a submodule of your own project, which alters the sys.path to import it,
you will have to adjust your code to take the changed directory structure into consideration.

Previously, you would put the path
 ./git-python/lib

into your syspath. All modules moved two levels up, which means that the 'git-python' directory
now is a package itself. This implies that the submodule's path must change so that the root
directory is called 'git'.

Your code must now put the directory containing the submodule into the sys.path.

For example, if you previously would have the following configuration:

 ./ext/git-python/lib/git/__init__.py

you would now change your submodule path to the following:

 ./ext/git

On the latets revision, the directory structure is changed so that
the git/__init__.py file is at the following path:

 ./ext/git/__init__.py

To be able to import git, you need to put ./ext into your sys.path.
