# Usage: generate-groups.sh <generators> <output-package> <apis-package> <groups-versions> ...
#
#   <generators>        the generators comma separated to run (deepcopy,defaulter,client,lister,informer) or "all".
#   <output-package>    the output package name (e.g. github.com/example/project/pkg/generated).
#   <apis-package>      the external types dir (e.g. github.com/example/api or github.com/example/project/pkg/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:
#   generate-groups.sh all             github.com/example/project/pkg/client github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1"
#   generate-groups.sh deepcopy,client github.com/example/project/pkg/client github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1"
