+
+    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:].
