Original description

To add global options, one can write code like this:

    def get_optparser(self):
        p = cmdln.Cmdln.get_optparser(self)
        p.add_option('-E', '--environment', dest='env',
                     help='path to virtualenv environment to use')
        p.set_defaults(env=None)
        return p

Wouldn't it be better to do this by using the same `@cmdln.option`
decorator but on the class itself rather than a method?

    @cmdln.option('-E', '--environment',  ...)
    class Foo(cmdln.Cmdln):
        ...

Thoughts?

(this would affect issue 2)
