This folder contains git hooks for the Graphics repository.
They can be installed by running install.sh.
It will (recursively) create a hard link of each file present in this folder and put it in the .git/hooks/ folder.
This manual installation step is required because the .git/ folder can't be pushed to the remote repository and therefore automatically be configured for all developers.
New types of hooks can be added by creating a script file (e.g. pre-push) at the root of this folder.
New hooks' logic should be put in a folder (pre-push.d/) and be called by the root file corresponding to the hook type so that the root files stay short and new hooks can be added easily.
