Spec parser

Hi Peter, hi folks,

I'm working on improving and automating our spec coverage tool[1] and Robin pointed out that Shepherd already had a pretty efficient spec parser[2].

Problem is it's tightly coupled with the rest of the Shepherd infrastructure.

Are there any plans to make this component standalone? I wouldn't mind giving it a go myself, but tests and docs are scarce.

Thanks,
