[Haskell-cafe] Package metadata format - notes from discussion

For reference, I have organized the major points of the discussion that happened earlier on haskell-cafe regarding package metadata format (cabal vs yaml, vs toml, vs hs). Take a look at this: https://github.com/harendra-kumar/package-metadata In my opinion, in the short term it might help if the cabal format is improved, the parser is modularized and detached from the cabal tool itself so that it can be used independently by any other tools wishing to do so. For long term possibility of change of format, I do not intend to pursue or investigate it further at this point of time but others who are interested are free to do so. -harendra
