Module Ecaml__.Hook

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.
