 """IPython Test Suite Runner.
 
 This module provides a main entry point to a user script to test IPython
 itself from the command line. There are two ways of running this script:
 
 1. With the syntax `iptest all`.  This runs our entire test suite by
    calling this script (with different arguments) recursively.  This
    causes modules and package to be tested in different processes, using nose
    or trial where appropriate.
 2. With the regular nose syntax, like `iptest -vvs IPython`.  In this form
    the script simply calls nose, but with special command line flags and
    plugins loaded.

       is passed, one process is used per CPU core. Default 1 (i.e. sequential)
 
     inc_slow : bool
       Include slow tests. By default, these tests aren't run.
 
-    slimerjs : bool
-      Use slimerjs if it's installed instead of phantomjs for casperjs tests.
-
     url : unicode
       Address:port to use when running the JS tests.
 
     xunit : bool
       Produce Xunit XML output. This is written to multiple foo.xunit.xml files.
 
     coverage : bool or str
       Measure code coverage from tests. True will store the raw coverage data,
       or pass 'html' or 'xml' to get reports.
 
     extra_args : list
       Extra arguments to pass to the test subprocesses, e.g. '-v'
