+// How to use:
+// go run make.go <flag>
+//
+// Flags:
+// <no flag>: Build code
+// -check: Run unit tests
+// -test: Run full suite of tests
+// -run: Run all-in-one server
+// -clean: Clean up a previous build
+// -release: Build official OpenShift release
+// -what: Specify a target directory to build
+// -tests: Specify a target directory to test
+// -goflags: Specify go tool flags. Use only
+// 	with equals sign eg. go run make.go -goflags=-v
+//  or go run make.go -goflags='-u -v' for multiple
+//  go flags
