The general command line structure is command [flags] subcommand [subflags] [argument] ... There's a class variable GlobalFlags which specifies the global flags options. Subcommands are defined by defining methods named do_<subcommand>. Flags for the subcommand are defined by defining class or instance variables named flags_<subcommand>. If there's no command, method default() is called. The __doc__ strings for the do_ methods are used for the usage message, printed after the general usage message which is the class variable UsageMessage. The class variable PostUsageMessage is printed after all the do_ methods' __doc__ strings. The method's return value can be a suggested exit status. [XXX Need to rewrite this to clarify it.] Common usage is to derive a class, instantiate it, and then call its run() method; by default this takes its arguments from sys.argv[1:]. s; usage: (name)s [flags] subcommand [subflags] [argument] ...t c C s d S( s& Constructor, present for completeness.N( ( t self( ( s( /usr/lib64/python2.7/Demo/pdist/cmdfw.pyt __init__# s c C s� d d l } d d l } | d k r4 | j d } n y | j | | j � \ } } Wn | j k ru } | j | � SX| j | � | s� | j � | j � S| d } d | } d | } y t | | � } Wn" t k r� | j d | f � SXy t | | � } Wn t k r d } n Xy | j | d | � \ } } Wn. | j k rp} | j d | t | � � SX| j � | | | � Sd S( s3 Process flags, subcommand and options, then run it.i����Ni i t do_t flags_s command %r unknownR s subcommand %s: ( t getoptt syst Nonet argvt GlobalFlagst errort usaget optionst readyt defaultt getattrt AttributeErrort str( R t argsR R t optst msgt cmdt mnamet fnamet methodt flags( ( s( /usr/lib64/python2.7/Demo/pdist/cmdfw.pyt run' s: c C sR | rN d d GHd GHx+ | D]# \ } } d G| Gd Gt | � GHq Wd d GHn d S( sW Process the options retrieved by getopt.
