The format of the menu_spec is:

[ menu_info, menu_info, ... ]

And the format of the menu_info is:

[
  [text, underline, configs], # menu button/entry (*1)
  [label, command, underline, accelerator, configs],   # command entry
  [label, TkVar_obj, underline, accelerator, configs], # checkbutton entry
  [label, [TkVar_obj, value], 
                     underline, accelerator, configs], # radiobutton entry
  [label, [[...menu_info...], [...menu_info...], ...], 
                     underline, accelerator, configs], # cascade entry (*2)
  '---', # separator
  ...
]

underline, accelerator, and configs are optional pearameters. Hashes are OK instead of Arrays. Then the entry type ('command', 'checkbutton', 'radiobutton' or 'cascade') is given by 'type' key (e.g. :type=>'cascade'). When type is 'cascade', an array of menu_info is acceptable for 'menu' key (then, create sub-menu).

NOTE: (*1)

If you want to make special menus (*.help for UNIX, *.system for Win, 
and *.apple for Mac), append 'menu_name'=>name (name is 'help' for UNIX, 
'system' for Win, and 'apple' for Mac) option to the configs hash of 
menu button/entry information.

NOTE: (*2)

If you want to configure a cascade menu, add :menu_config=>{...configs..}
to the configs of the cascade entry.
