First step in the module design
The new module design allows modules to be registered by adding them
to settings.MODULES. Currently modules cannot do a lot (they can
register with the sidebar and the sitemap), but the structure is in
place.
Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
