-Metadata-Version: 1.1

-Description: Coverage.py measures code coverage, typically 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.
-        
-        Coverage.py runs on Pythons 2.3 through 3.3, and PyPy 1.9.
-        
-        Documentation is at `nedbatchelder.com <http://nedbatchelder.com/code/coverage>`_.  Code repository and issue
-        tracker are at `bitbucket.org <http://bitbucket.org/ned/coveragepy>`_.
-        
-        New in 3.6: ``--fail-under``, and >20 bugs closed.
-        
-        New in 3.5: Branch coverage exclusions, keyboard shortcuts in HTML report.
-        
-        New in 3.4: Better control over source to measure, and unexecuted files
-        can be reported.
-        
-        New in 3.3: .coveragerc files.
-        
-        New in 3.2: Branch coverage!
