An interesting project by Paul Sidnell:
ofexport is a command line utility that reads and exports the task database from the OmniFocus application.
While similar to Robin Trew's export utility, ofexport has a series of extra options worth trying out. I'm particularly intrigued by the control you can have on date and calendar filters, as well as regular expressions. I constantly check on my OmniFocus todos through the calendar, so I'll make sure to test ofexport. [via Sven Fechner]
