-"""Marshal is a tool for generating marshalling interfaces for Go types.
-
-The recommended way is to use the go_library rule defined below with mostly
-identical configuration as the native go_library rule.
-
-load("//tools/go_marshal:defs.bzl", "go_library")
-
-go_library(
-    name = "foo",
-    srcs = ["foo.go"],
-)
-
-Under the hood, the go_marshal rule is used to generate a file that will
-appear in a Go target; the output file should appear explicitly in a srcs list.
-For example (the above is still the preferred way):
-
-load("//tools/go_marshal:defs.bzl", "go_marshal")
-
-go_marshal(
-    name = "foo_abi",
-    srcs = ["foo.go"],
-    out = "foo_abi.go",
-    package = "foo",
-)
-
-go_library(
-    name = "foo",
-    srcs = [
-        "foo.go",
