+Metadata-Version: 1.1
+Name: coverage
+Version: 3.7
+Summary: Code coverage measurement for Python
+Home-page: http://nedbatchelder.com/code/coverage
+Author: Ned Batchelder and others
+Author-email: ned@nedbatchelder.com
+License: BSD
+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 on `Bitbucket <http://bitbucket.org/ned/coveragepy>`_, with a
+        mirrored repo on `Github <https://github.com/nedbat/coveragepy>`_.
+        
+        New in 3.7: ``--debug``, and 12 bugs closed.
+        
+        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!
