+// This file contains the beginnings of static code generation.
+// It doesn't generate anything useful, yet, but can be used as a starting point.
+
+// TBD:
+// - Generate a single file or scaffold an entire project directory? Both?
+// - Targets: ES5, ES6, TypeScript? CommonJS? AMD?
+// - Is there a need for a minimal runtime composed only of Reader/Writer/minimal util?
+// - What about generating comments and typescript definitions for non-ts targets?
