+Usage: $(basename "$0") <generators> <output-package> <internal-apis-package> <extensiona-apis-package> <groups-versions> ...
+
+  <generators>        the generators comma separated to run (deepcopy,defaulter,conversion,client,lister,informer,openapi) or "all".
+  <output-package>    the output package name (e.g. github.com/example/project/pkg/generated).
+  <int-apis-package>  the internal types dir (e.g. github.com/example/project/pkg/apis).
+  <ext-apis-package>  the external types dir (e.g. github.com/example/project/pkg/apis or githubcom/example/apis).
+  <groups-versions>   the groups and their versions in the format "groupA:v1,v2 groupB:v1 groupC:v2", relative
+                      to <api-package>.
+  ...                 arbitrary flags passed to all generator binaries.
+
+Examples:
+  $(basename "$0") all                           github.com/example/project/pkg/client github.com/example/project/pkg/apis github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1"
