A pure-ruby growl notifier for UDP and GNTP growl protocols. ruby-growl allows you to perform Growl notifications from machines without growl installed (for example, non-OSX machines). What is growl? Growl is a really cool "global notification system originally for Mac OS X". You can receive Growl notifications on various platforms and send them from any machine that runs Ruby. OS X: http://growl.info Windows: http://www.growlforwindows.com/gfw/ Linux: http://github.com/mattn/growl-for-linux ruby-growl also contains a command-line notification tool named 'growl'. It is almost completely option-compatible with growlnotify. (All except for -p is supported, use --priority instead.)
