A quick way to do this would be the directory_watcher gem. It watches
files in a directory and notifies you when those files change -- add,
modified, deleted. There is a fourth file notification event called
"stable" -- this is sent when the file has remained un-modified for X
amount of time.

It's all ruby code, so it should work on Windows and Unix equally well.
