[tex-live] Catalogue sources

[Karl Berry]

    we get this quite often, actually: people docstrip something and then
    reckon people don't need the .dtx

And do you consistently use nosource in those cases?  Somehow it hasn't
come up before.

    the licence statement in the readmes is confusing -- says something like
      "artistic/gpl, version 2"
    which could also mean "artistic1/gpl2", i.e., not ok.

On the contrary, artistic1/gpl2 is ok (because of the gpl2 part :).
