# setup.py for coverage.py
"""Code coverage measurement for Python
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 <%s>`_. 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!
