System.INotify

A Haskell binding to INotify. See http://www.kernel.org/pub/linux/kernel/people/rml/inotify/ and man inotify.

Use initINotify to get a INotify, then use addWatch to add a watch on a file or directory. Select which events you're interested in with EventVariety, which corresponds to the Event events.

Use removeWatch once you don't want to watch a file any more.
