2. There is currently no code that I am aware of that implements this spec. I don't believe distlib does (yet - give Vinay 5 minutes and who knows? :-)), pkgresources as I said implements a different format, and distutils2, apart from being a big dependency to cover just this point, only matches the version (not the project name) and presumably does so using the distutils2 version ordering (which is incompatible with Metadata 2.0).

It should be alongside the version stuff, atleast it was in distutils2.

Yes, sorry - distlib does include code for this:

I was looking for the term "requirement" which is not used, and missed it. (Either that or Vinay's been borrowing the time machine keys again!) Paul
