Requirements:

• https://github.com/ggreer/fsevents-tools
  Clone/download, cd and then run source autogen.sh (you may need to brew install automake and/or brew install autoconf, followed by sudo make install.
• Mountain Lion (for notifications) with terminal-notifier (sudo gem install terminal-notifier). Could be easily modified to use Growl or whatever for earlier versions of Mac OS.
