-### Begin kustomize plugin rules.
-#
-# The rules to deal with builtin plugins are a bit
-# complicated because
-#
-# - Every builtin plugin is a Go plugin -
-#   meaning it gets its own module directory
-#   (outside of the api module) with Go
-#   code in a 'main' package per Go plugin rules.
-# - kustomize locates plugins using the
-#   'apiVersion' and 'kind' fields from the
-#   plugin config file.
-# - k8s wants CamelCase in 'kind' fields.
-# - The module name (the last name in the path)
-#   must be the lowercased 'kind' of the
-#   plugin because Go and related tools
-#   demand lowercase in import paths, but
-#   allow CamelCase in file names.
-# - the generated code must live in the api
-#   module (it's linked into the api).
 
-# Where all generated builtin plugin code should go.
