Re: trn license

Okay, the reference to the bison skeleton is probably just copyright
file junk, in that case.  But I still worry about this part:

-- The "clarification" seems to contradict the sentence it clarifies;
   "it is not sold, rented, traded or otherwise marketed" pretty clearly
   forbids what is described here.
-- Apparently, Larry Wall never replied to Ian's query.

Oh, and no license is given for this:
