[DUG] Open source licences

[Steven Knight]

Think I am wrong because further down in the page you refered to, I found this:
==========================
If a library is released under the GPL (not the LGPL), does that mean that any program which uses it has to be under the GPL? 
Yes, because the program as it is actually run includes the library. 
==========================
