I would just as soon do away with "type=='pip'" and instead have a standard `pip install` wrapper script that a package's spkg-install symlinks too. Maybe still something in there somewhere to note that it's not a standard sage package and is instead installed from PyPI, but I don't know that the package type is the appropriate metadata for that, though I can see why it was used originally. (Maybe such a package could be called "external"--i.e. not really part of sage at all, and having dependencies not necessarily from sage either--in principle such an external package could come from many possible sources too, not just pip/PyPI--but that's getting ahead of myself). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
