While checking the contents of our `perl' package, I noticed the following:
/* NOTE: this is derived from Henry Spencer's regexp code, and should not
* confused with the original package (see point 3 below). Thanks, Henry!
/* Additional note: this code is very heavily munged from Henry's version
* in places. In some spots I've traded clarity for efficiency, so don't
* blame Henry for some of the lack of readability.
/* The names of the functions have been changed from regcomp and
* regexec to pregcomp and pregexec in order to avoid conflicts
* with the POSIX routines of the same names.
* pregcomp and pregexec -- regsub and regerror are not used in perl

I looked but couldn't find any common name for this license
of Henry's. Is it on our list? Is it free? What name should
I use in the License tag?
For many years now, the gap package has bundled 3 sets of data files
describing mathematical structures (groups). I am working on updating
the Fedora package to the latest release, version 4.10.0. In this
version, those 3 sets of data files have been split out into
separately distributed entities, with their own home pages and release
schedules. They all grew new license terms, too. I am worried about
the license on one of them, transgrp (see
https://www.gap-system.org/Packages/transgrp.html). It reads:
This library containing data and access functions, its parts are licensed in
- In the belief that mathematical truth is universal and not owned or
licenseable, the mathematical content can only be acknowledged: Groups of
degree up to 15 are as described in Conway/Hulpke/McKay (LMS. Journal
Comp. Math, Vol 1.) and the sources quoted therein.
Groups of degree up to 30 were determined by Hulpke (J.Symb.Comp). Groups of
degree 32 were determined by Cannon and Holt (Exp.Math.). Groups of degree
33-47 were determined by Holt.
- The actual way of storing the groups and associated data, and the
arrangement of the groups, is licensed under the artistic license 2.0:
If you distribute software that claims to use or include the GAP transitive
groups library it must include the actual data lists verbatim.
- The functions accessing the data files are licensed under GPL2 and under
I would call this license "Artistic 2.0 and (GPLv2 or GPLv3)", except
that I am worried about the sentence that begins "If you distribute
software...". That sentence refers to the data files. There is no
code in them, just formal descriptions of mathematical structures. Is
that sentence a problem?

As I understand it, the requirement is not just to make the source code
available, but to make it available _under the terms of this license_.
As suggested, please take further dicussion to legal(a)lists.fedoraproject.org
