-        * `pexcept` - print Exception message to sys.stderr. If debug is true, print exception traceback if one exists.
-    * Removed color parameters from `poutput` and `perror` since more powerful styles now exist. See the docstrings
-    of these methods for more information on applying styles to output messages.
