Some sort of exception needs to spelled out if it is the developers
intention that Vtcl output NOT be GPL'd.
The Linux kernel has an exception at the top of the copy of the GPL that
comes with it making it clear that programs that use kernel services
aren't GPL and that only version 2 of the license applies.
I don't see why the language of the bison exception can't be used,
rewritten for Vtcl:
"As a special exception, the program generated by Vtcl may be used
without restriction. This special exception was added by <name here> in
version 1.2.x of Vtcl."
Or maybe
"Visual Tcl is licensed under the GNU General Public License Version 2.
As a special exception, the output produced by Visual Tcl may be used
without restriction. This special exception was added by <name here> in
version 1.2.3 of Visual Tcl."
(Note I'm doing it to 1.2.2 here :)
I think it should be added to the top of the copy of the GPL that is
distributed with Vtcl emitted into the generated program.
