This is a simple commandline utility to watch a web page that's not working and send me some notifications to let me know when it starts working again.
Currently it supports growl and webhooks. Could do more in the future.
Create a notify.json from the example, but with your stuff in it. It can have as many or as few notifiers as you want (if it's empty, the process will just exit when it's done).
run the tool:
./urlwatch http://www.google.com/
