Interesting note on the copyright terms page:
You are encouraged to redistribute Matpack under the GNU General
Public License, but you should REFRAIN FROM DISTRIBUTING MODIFIED
VERSIONS of the library. This is especially important for numerical
algorithms, library interfaces and for tools. Experience shows that
hot `bug fixes' and `improvements' often have severe side effects or
implications for correctness and integrity in circumstances other
users may rely on. If you have bug fixes, improvements, new
algorithms, or updates for the online documentation, please send your
suggestion to the author. I will include bug fixes and contributions
in the next Matpack distribution.
Hmm. GPL, but "refrain from distributing modified versions" (the
all-caps emphasis is there in the original)? It also has non-free
documentation, and the author seems to confuse "commercial" with
"proprietary". The source files also include comments like
Note that distributing Matpack 'bundled' in with any product is
considered to be a 'commercial purpose'.
The software may be modified for your own purposes, but modified
versions may not be distributed without prior consent of the author.
So I guess it is not really GPL.
