Description: Hooks are user customizable executables that may be run at specific points during the site generation process.

To make the static site more dynamic(pun intended) Pagegen can run executables (hooks) at preset times, during the generation process.

To enable a hook make the appropriate hook file executable (``chmod +x hooks/hook_file``).

.. tip::

	Run ``pagegen --init`` on empty directory and see ``hooks`` directory for examples. To use an example remove ``.example`` and ensure the script is executable.

Run one of the example hooks to see the available environment variables. All settings in the current ``site.conf`` environment are set, named ``PAGEGEN_<setting name>``.

::

	cd hooks
	mv pre_generate.example pre_generate
	chmod +x pre_generate
	pagegen -g <environment>
