The upstream author is: 

Marc Lehmann <pcg@goof.com>, the original uulib library was written by
Frank Pilhofer <fp@informatik.uni-frankfurt.de>..

This interface is distributed under the same license as perl itself, i.e.
either the Artistic License (/usr/share/common-licenses/Artistic) or the
GPL (/usr/share/common-licenses/GPL).

However, the uulib library itself (see the subdirectory uulib) is ONLY
distributed under the GENERAL PUBLIC LICENSE. Depending on how you link it
together (normally static) this makes the whole package fall under the GPL.

If you make modifications, please consider sending them to me,
