Flimm · theskumar · commit 07fffa1c59cb · 2018-03-07T14:56:43.000+05:30
The test is not run in Python 3.3 because of this bug: https://sourceforge.net/p/docutils/bugs/270/ Having valid RST is important so that Pypi's web interface interprets the RST correctly and display long_description in a pretty format.
