Hi there, Here's (finally) a collection and summary of all of the known broken items in Parrot right now as a patch to create BROKEN.pod in the top level directory. If this isn't the right name or place to put the file, that's fine.
I'll check this in in two days with regard to feedback from anyone whose opinion matters and what to call it and where to put it, if my initial choice isn't perfect. -- c
