In OS X Snow Leopard I used the growlnotify utility that was included in the Growl 1.2 SDK. I've downloaded the SDK for Growl 1.3 but I don't see any growlnotify utility included (am I missing it?)
Growl 1.3 also supports GNTP, which I have not yet used, however OS X (all versions) have support for many languages such as php, ruby, perl, python, etc. and I have heard that there are some good GNTP libraries out there.
So what methods can I use to growl from the command line in OS X Lion?
Examples are very much appreciated.
