python-coverage-dbg 3.6-0ubuntu5 (amd64 binary) in ubuntu saucy

 The ‘coverage’ library measures which parts (statements) of a Python
 program are executed while it is run. This is useful for testing:
 those parts of a program that are not executed by the tests have not
 been tested.

 This package contains the debugging symbols for the C extension
 libraries in ‘python-coverage’.
