ANN: crone - cron in Erlang (sort of)

[Sean Hinde]

Well, here's one I wrote earlier.

The API is unfinished (stuck somewhat between two methods) but it does seem
to work well enough.

This one sends a tick to itself every minute and does any jobs which are
scheduled at that time. There are some (slightly incorrect) docs in the code

You can also have a job run at startup which returns a state which is passed
through future invocations.

Someone might find it useful.. cron.conf is in the priv dir
