We, the developers, hold copyright. That allows us to change the license as we are
discussing now. Thus, it also means that we can grant license to others, if I understand
correctly. In other words, we can stay GPL and grant another license to someone when they
ask. So that's another option.
I'm still not clear with GPL what defines a "derivative" work. Under GPL could one provide,
say, a proprietary software product, yet include swish-e for searching their HTML docs, as
long as they say it's swish-e and provide a copy of the GPL license? Would sharing a CD-ROM
with swish-e force their code to be GPL? It doesn't under LGPL, from my reading. Doesn't
seem like it under GPL, either.
Then there's this bit:
Section 5 of the LGPL says:
5. A program that contains no derivative of any portion of the Library, but is designed to
work with the Library by being compiled or linked with it, is called a "work that uses the
Library". Such a work, in isolation, is not a derivative work of the Library, and therefore
falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that
is a derivative of the Library (because it contains portions of the Library), rather than a
"work that uses the library". The executable is therefore covered by this License. Section 6
states terms for distribution of such executables.
Huh? Oh that's real clear.
I'm having a hard time comparing that to Swish-e. Swish-e has a C library. Actually,
almost all the code is part of a library. So the line between library and program is not so
Now where did I put that gin?
