+Buildid displays or updates the build ID stored in a Go package or binary.
+
+Usage:
+
+	go tool buildid [-w] file
+
+By default, buildid prints the build ID found in the named file.
+If the -w option is given, buildid rewrites the build ID found in
+the file to accurately record a content hash of the file.
+
+This tool is only intended for use by the go command or
+other build systems.
