Bugs known in version 0.02
* Broken Condition handling - it will probably work on summaries, but is ultimately broken on detail pages
* cover_report is very noisy when it cleans the cover_db directory
* no warning about cover_db being wiped out. Maybe, there should be one?
* File's total coverage sometimes is counted as AND, instead of OR from all runs.
This happens mostly, if parts of the module are re-defined in tests.
Seems to be a problem in the way original Devel::Cover stores coverage metrics.
