Your files are ok.  But all of them have the LGPL permission to copy
statements.  I thought you were going to release the sim under the
GPL?

I think you don't understand what I mean.  Maybe I wasn't clear
enough.

If they release their code under the LGPL they still have to give the
code with it (when they distribute their code).

This is also with the GPL.

They don't have to share their code if they don't distribute their
code.

So if you release the library under the GPL this wouldn't spoil the
fun.

Everbody can change it and keep it secret, but it still remains free
software.  They only have to share their code if they plan to
distribute their code.

If you would choose the LPGL, then this is also true.  BUT somebody
else can link your library with a non free program.  And distribute
that non free software without sharing the code of the non free
program.  He still has to distribute the code of your library.

If your libray would be released under the GPL then the non free
program must become free software.

U see?

Vincent is wrong.
