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. cCsddlm}t||s+tdn|jtkrFtdn||_|jd|_ |j |_ d|_ d|_ d|_dS(sCreate and initialize a new Command object.
