A few functions to make working with python inside git repos easier.
gitpath.root() returns the absolute path of the repository root
directory
gitpath.abspath(_rel_path_) returns an absolute path for a path given relative to the
root directory,
so assuming, this repo resites in /home/maxnoe/python-gitpath:
import gitpath
print(gitpath.abspath('setup.py'))
Will give you:
/home/maxnoe/python-gitpath/setup.py
