"""distutils.errors

Provides exceptions used by the Distutils modules.  Note that Distutils
modules may raise standard exceptions; in particular, SystemExit is
usually raised for errors that are obviously the end-user's fault
(eg. bad command-line arguments).

This module safe to use in "from ... import *" mode; it only exports
symbols whose names start with "Distutils" and end with "Error"."""
