 #
 # (none)	Setup GOPATH and build in GOPATH mode.
+# build		Indicates that Go is used at build time as a part of
+#		make/CMake build. This will setup build environment like
+#		GO_ENV, GO_BUILDFLAGS but avoid creating post-extract, do-build
+#		and do-install targets.
 # modules	If the upstream uses Go modules, this can be set to build
 #		in modules-aware mode.
+# run		Indicates that Go is needed at run time and adds it to
+#		RUN_DEPENDS.
 #
 # You can set the following variables to control the process.
