That's nothing to do with dual-licencing issues, though. Dual licensing
doesn't alter the terms of either license, it only specifies the terms
in which you may accept to be bound by the license.

No, free but restricted essentially means freeware pretty much, which
the author might have 'very kindly' allowed you to do more with :(. Dual
licensed stuff, like Perl, just comes up as 'GPL & Artistic'. It's still
Free software - because you can get it as GPL - it's just /also/
non-Free / free / commercial / whatever else they licence it with.

BTW - I did have a look for examples of dual licensing. GPL & Artistic
seems to be *the* major 'dual license' example. I couldn't find a
*single* example of a dual scheme where one partner wasn't the GPL -
does anyone know of any examples??
