> Since Meataxe is GPLv2 and you compile against it, your package is
GPLv2. I assume you are releasing your *code* under GPLv2+, but the
package itself inherits what Meataxe is. So, '''must''' is only if you
want your optional package to by GPLv2+. There are all kinds of licenses
in the optional spkg's though.

I should also say that your SPKG.txt file has merely the generic blurb

However, if memory serves, the FSF says that if you do not specify the
version of the
GPL then it is *assumed* to be the latest version (which is at this date
GPLv3).
This is not what you want, of course.

But HOW can I put them under a licence?

For the internet files, you could have a COPYING file in the same
directory on the server.
