== Test plug-in ==

 There are two main uses for plug-ins in cppunit:
 * writing unit tests in plug-ins
 * customizing/extending cppunit at run-time

 Unit test plug-ins are already handled by linking against a dll build of cppunit 2. The static registry is shared among users of the dll. A simple runner needed to be written though.

 Customization/extension should provide more flexibility than in cppunit 1. A very interesting goal to achieve would be to allow graphic test runner to be a simple 'extension', though this might be complex to achieve.
