class_docstr: Abstract base class for defining command classes, the "worker bees"
  of the Distutils.  A useful analogy for command classes is to think of
  them as subroutines with local variables called "options".  The options
  are "declared" in 'initialize_options()' and "defined" (given their
  final values, aka "finalized") in 'finalize_options()', both of which
  must be defined by every command class.  The distinction between the
  two is necessary because option values might come from the outside
  world (command line, config file, ...), and any options dependent on
  other options must be computed *after* these outside influences have
  been processed -- hence 'finalize_options()'.  The "body" of the
  subroutine, where it does all its work based on the values of its
  options, is the 'run()' method, which must also be implemented by every
  command class.

docstr: Set default values for all the options that this command
  supports.  Note that these defaults may be overridden by other
  commands, by the setup script, by config files, or by the
  command-line.  Thus, this is not the place to code dependencies
  between options; generally, 'initialize_options()' implementations
  are just a bunch of "self.foo = None" assignments.
  
  This method must be implemented by all command classes.
