A hook is a variable where you can store a function or functions to be called on a particular occasion by an existing program. Emacs provides hooks for the sake of customization.

Hooks installed through Ecaml are wrapped in an exception handler that prints the error to the *Messages* buffer and exits the function normally.

If one_shot is true, the hook will be removed after the first time it runs.

Use this instead of (describe-variable 'after-init-hook), since the latter occurs before command-line arguments are handled (and therefore before the OCaml runtime is initialized).
