python - Defining common options for sub-commands with plac -

my question follow-up this question. shows how can use plac automatically generate command-line interface sub-commands representing each function.

is possible tell plac options common sub-commands, , viewed 'global' options? in fact, these options should have meaning without sub-command.

as example, might have svn checkout , svn update sub-commands, svn -v or svn --version command.

a couple of years ago set multiprocessing script using plac. had multiple commands overlapping sets of arguments. i'll try abstract did

class interface(object):     commands = ['fn1','fn2',...]     dict1 = dict(quiet=(...), dryrun=(...), ...)     dict2 = dict()     dict3 = dict()      dict1.update(dict2)     @plac.annotations(**dict1)     def fn1(self, dryrun, quiet, ...)         ...     @plac.annotations(foo=(...), **dict2)     def fn2(self, foo, ...)         ...     @plac.annotations(**dict2)     def fn3(self, ...)         ... 

so while arguments each function had spelled out in full, annotations built mix , matching various dictionaries.
