Dear Cabal developers,
spurred by this discussion on haskell-cafe [1], I attach a small patch
on licence warnings. It:
- reverts AllRightsReserved as PackageDistInexcusable, as it was
before this commit [2].
Reading the comments in Check.hs, this datatype is for issues which
"[are] OK in the author's environment but [are] almost certain to be
a portability problems for other environments", which I think it is
the case.
- adds a PackageDistSuspicious warning on OtherLicense. The text of
the warning encourages the developer to choose from licences
suggested by the OSI or FSF, if they don't want to use a licence
recognised by cabal.
Thanks
-Francesco
