+
+This is a tiny Node script that is used by doerg. For each CBOR-encoded value on stdin (a "command"), a response value is spit to stdout.
+
+Currently, the following commands are supported:
+- Any string: Return the Temml-rendered MathML code as a string (inline).
+- An array with a single string element: Return the Temml-rendered MathML code as a string (display).
+If something goes wrong, either of these commands may return an object of form
+#+begin_src json
+  {"type": "error"
+  ,"error": «error object»}
