"""distutils.command.config

Implements the Distutils 'config' command, a (mostly) empty command class
that exists mainly to be sub-classed by specific module distributions and
applications.  The idea is that while every "config" command is different,
at least they're all named the same, and users always see "config" in the
list of standard commands.  Also, this is a good place to put common
configure-like tasks: "try to compile this C code", or "figure out where
this header file lives".
