Hi, I do not know whether Debian considers the Douglas Crockford license (or, if you will, copyrightable material covered by the Douglas Crockford license) to be nonfree. Fedora classifies this license as nonfree. The first comment on https://bitbucket.org/dcs/jsmin/raw/e0fa31661e18aaaa37285f22ae708dde3880a8d8/jsmin/__init__.py says: # This code is original from jsmin by Douglas Crockford, it was translated to # Python by Baruch Even. It was rewritten by Dave St.Germain for speed. I think "original from jsmin" should be understood as meaning "originally from jsmin". It is reasonable to presume that the referenced 'translation' by Baruch Even is a derivative work of the original jsmin. There's no particular reason to assume that Dave St. Germain's 'rewriting' eliminated any derivative work relationship. Here https://bitbucket.org/dcs/jsmin/issue/7/include-license-file Dave says I've never seen the original Crockford code, but the notice was on the jsmin.py that I modified. My version actually has no resemblance to the older jsmin, so one could consider it a "clean room implementation". It's clear that Dave did see the Baruch Even code, since he modified it. He also says "the credits in the source file are there to honor the inspiration for the source, not the actual implementation." None of this makes me inclined to see Dave's code as something other than a derivative work of Crockford's jsmin.c. I have never really attempted to compare the two though.
