     ### Options configuration

-    # Hi, dear developer! Are you trying to add a new subcommand, or
-    # to add some options?  Well, keep in mind that an option CAN'T
-    # have differente meanings/behaviour in different subcommands.
-
-    # For example, "-s" means "size" and accept an argument. If you are tempted to add
-    # an option "-s" (that means, for example "silent", and doesn't accept an argument)
-    #           DON'T DO IT!
-
-    #  There are two reasons for that:
-    #       I. usability; user expect that "-s" is "size"
-    #    II. Option parsing WILL EXPLODE if you do this kind of bad things
-    #            (it will say "option defined more than once, and he's right")
     #
-    #    If you want to use the same option in multiple commands then
-    #    you can only use the non-abbreviated long-option version like:
-    #    -force and NOT -f
