I would like more information/feedback on this.

Somebody in the geosciences wrote a matlab utility of marginal use to
me (for an application that has nothing to do with the geosciences) .
It is obvious they are in the geosciences, as the utility assumes km as
the distance measurement.  I got sidetracked by other things, but I
think my local files were more than 4 times as big as the original
matlab source.  And I am talking code, not comments.

If I do a global search and replace on variable names, the code is
still the same.  To me.  The core of the code is useful.  And anyone
reading a textbook in geophysics could probably produce similar code.
For me, things were missing.  So I am adding code, and trying to do so
in a way that I don't hard code "kilometers" into things.

What has to change, to break the copyright tie to this library of
matlab things, to make things unique?
