+These hooks for git make it possible to efficiently use Powerpoint in a git repository.
+
+When creating or cloning the repository locally run setup.sh first to copy the hook scripts into the .git folder.
+
+Everytime a .pptx file is committed its unzipped contents will be committed instead.
+After a pull the file is zipped back into a .pptx.
