This is indeed quite interesting. I was just wondering about the
license of your code.
As far as I understand it, the original JAMA is "public domain" hence
even more permissaive than boost license:
Is it also the case for ublasJama? I was not able to see any license
information on your webpage nor in the source code:
It would be nice to add, for example, a LICENSE.txt file with the
relevant information to your source package. The best for me would of
course be to find an OSI approved license
such as the MIT, Boost or BSD one.
