This package is officially deprecated.
The directories here that are submodules are the packages I think are useful enough to warrant maintainership. They are all their own repos and have been uploaded to hackage separately. In accordance with this, the yesod-comments package on hackage now directly depends on them and not this meta-package.
Everyone should switch to using those packages independently and not rely on, expect, or link to the "-goodies" meta package.
That said, if anyone thinks an overall -meta is useful and is willing to maintain it, I won't stop you -- feel free to fork, update and upload.
