Original description

It would be nice if cmdln supported groups for commands, such that the help 
for the tool is printed separated by sections.

Somewhat like:

class Tool(cmdln.Cmdln):
  @cmdln.section("colors")
  def do_red(...):
    ...
  ...
  @cmdln.section("metasyntactic")
  def do_foo(...):
    ...
  @cmdln.section("metasyntactic")
  def do_bar(...):
    ...
  ...

$ tool help
Usage:
    tool ...

Commands:
  colors:
    red      The red color.
    green    The green color.
    blue     The blue color.

  metasyntactic:
    foo      Does foo.
    bar      Does bar.
    baz      Does baz.
