cola or git cola is a highly caffeinated GIT GUI (Graphical User Interface) written in Python.
BUILDING FROM SOURCE
Normally you can just do "make install" to install git-cola in your $HOME directory ($HOME/bin, $HOME/lib, etc). If you want to do a global install you can do
# make prefix=/usr install
You can also run git-cola without installing it. It is designed to run directly out of the source tree This is the best way to run git-cola when you're modifying the code.
