Encouraged by Andy Schott's Safari to OmniFocus AppleScript example, I wrote a command line Ruby program to import tasks defined in YAML files.
For example:
% cat tasks.yml

note: Cherry 2
project: Auto
% of-import-yaml tasks.yml

Importing tasks seems to be quite a common request here, so I thought I'd post this in case other people find it useful even though it's very rough and ready code.
