What is the difference between a "Threaded version" and "Non Threaded" packages?
Eg. I have
libqt3-mt-dev 3.2.3-2 Qt development files (Threaded)
libqt3c102-mt 3.2.3-2 Qt GUI Library (Threaded runtime version)
libqt3-dev <none> (no description available)
What's the difference between threaded and non-threaded version?
