fs-watcher v0.2.1

watcher

Based upon Mikeal Rogers' watch library.

Watch a file tree and emit appropriate events for various changes. Extends EventEmitter. Uses FS.watch to monitor files for change, and re-scans directories periodicly to detect new creations and deletions.

Polling allows watcher to function on most operating systems where FS.watch or FS.watchFile are not fully supported or have inconsistant behavior. FS.watch is still used to monitor file changes asynchronously.
