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. cCsbddlm}t||std|jtkr0td||_|jd|_ |j |_ d|_ d|_ d|_ dS)zCreate and initialize a new Command object.

"Undefined" here means "is None", which is the convention used to indicate that an option has not been changed between 'initialize_options()' and 'finalize_options()'. Usually called from 'finalize_options()' for options that depend on some other command rather than another option of the same command. 'src_cmd' is the other command from which option values will be taken (a command object will be created for it if necessary); the remaining arguments are '(src_option,dst_option)' tuples which mean "take the value of 'src_option' in the 'src_cmd' command object, and copy it to 'dst_option' in the current command object".
