Commented Unassigned: addSynSymbol is not defined [13549]

I have tried both the most recent beta and alpha versions of pykd, but it appears that the API function addSynSymbol is not defined. What happened to it? Is the documentation just wrong, and this function is no longer supported? Is there some extra step I need to perform in order for addSynSymbol to be available?

Indeed, synthetic symbols were not merged from pykd 0.2.x to pykd 0.3.x. It is not difficult to do (if they really need)
