            Bug ID: 22195
           Summary: Provide a help() method to gdb.Command that overrides
                    the docstring
           Product: gdb
           Version: 7.11.1
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: python
          Assignee: unassigned at sourceware dot org
          Reporter: ciro.santilli at gmail dot com
  Target Milestone: ---

I want to use pythons argparse for command parameter handling after
gdb.string_to_argv

If I had a method:

    define help():

that would override the class docstring for:

    help mycmd

I could return:

    return parser.format_usage()

there and everything would be DRY and beautiful.
