'set_final_options()' to 'initialize_options()' and 'finalize_options()'.

"""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 'set_default_options()'
and "initialized" (given their real values) in
'set_final_options()', both of which must be defined by every
"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, option file, ...), and any options dependent on other
options must be computed *after* these outside influences have
been processed -- hence 'set_final_options()'. The "body" of the
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."""
