My understanding of the wording for part 1 was carefully designed so
that Perl's Artistic License did not violate it. Here is the section
in question of that license, with *'s added to show the tricky bit.:
You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this
Package. ***You may not charge a fee for this Package itself. However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial)
software distribution provided that you do not advertise this Package
as a product of your own.*** You may embed this Package's interpreter
within an executable of yours (by linking); this shall be construed as
a mere form of aggregation, provided that the complete Standard
Version of the interpreter is so embedded.
Cheers,
Ben
