scripts without modifying either the distutils installation or the setup.py scripts of packages with which the new commands will be used. Specifically, an option is added to distutils that allows additional packages to be searched for command implementations in addition to distutils.command. The additional packages can be specified on the command line or via the installation or personal configuration files already loaded by distutils. For discussion, see the thread starting with: http://mail.python.org/pipermail/distutils-sig/2004-August/004112.html This closes SF patch #102241.
