"""This plugin provides test timings to identify which tests might be
taking the most. From this information, it might be useful to couple
individual tests nose's `--with-profile` option to profile problematic
tests.
 
This plugin is heavily influenced by nose's `xunit` plugin.
 
Add this command to the way you execute nose::
 
--with-test-timer
 
After all tests are executed, they will be sorted in ascending order.
