    26  Usage: $(basename $0) <generators> <client-package> <apis-package> <groups-versions> ...
    27  
    28    <generators>        the generators comma separated to run (deepcopy,defaulter,client,lister,informer) or "all".
    29    <client-package>    the client package dir (e.g. github.com/example/project/pkg/clientset).
    30    <apis-package>      the external types dir (e.g. github.com/example/api or github.com/example/project/pkg/apis).
    31    <groups-versions>   the groups and their versions in the format "groupA:v1,v2 groupB:v1 groupC:v2", relative
    32                        to <api-package>.
    33    ...                 arbitrary flags passed to all generator binaries.
    34  
    35  
    36  Examples:
    37    $(basename $0) all             github.com/example/project/pkg/client github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1"
