Pip : Install a specific github repo tag or branch

I came across a rather simple problem lately : how to install one of my github hosted repo's specific tag using pip.

It can be very usefull when it comes to add one of your project's tag to a requirements.txt for example.

Here's how you do it :

pip install -e git://github.com/{ username }/{ reponame }.git@{ tag name }#egg={ desired egg name }

Thanks to CodeIntel who posted the trick
