 2
 3Provides exceptions used by the Distutils modules.  Note that Distutils
 4modules may raise standard exceptions; in particular, SystemExit is
 5usually raised for errors that are obviously the end-user's fault
 6(eg. bad command-line arguments).
 7
 8This module is safe to use in "from ... import *" mode; it only exports
 9symbols whose names start with "Distutils" and end with "Error"."""

11# This module should be kept compatible with Python 2.1.
