-### 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.
-pGen=api/builtins
-# Where the builtin Go plugin modules live.

-//   TODO: Modify kyaml/yaml/PathGetter to allow this.
-//   The value will be inserted into the array at the given position,
-//   shifting other contents. To instead replace an array entry, use
-//   an implementation of an IETF RFC 6902 Replace operation.
-//
-// For the common case of a filepath in the field value, and a desire

-	// At the time of writing, Value's value should be a simple string,

-	//   If _i_ is > 0, then it's assumed that
-	//   - 'Value' is a string that can work as a directory or file name,
-	//   - the field value intended for replacement holds a filepath.
-	//
-	// The filepath is split into a string slice, the value is inserted
-	// at position [i-1], shifting the rest of the path to the right.
-	// A value of i==1 puts the new value at the start of the path.
