Comment 1 for bug 692480

The official docs people point to is https://dev.launchpad.net/LEP/FeatureFlags

Which is a rambling LEP containing details irrelevant to implementers and assumes knowledge that a newb doesn't have.
There's no tips for debugging when feature flags don't work.

A branch I was working on has been blocked for several months because I can't get feature flags working, and the little ambiguities in the documentation make me uncertain whether it's my own lack of knowledge about feature flags, or something more fundamental. Every couple weeks I try again, banging on it for several hours with no results. I've asked people for help, but they don't know either. To say it's frustratingly hard is an understatement.
