 The only "API" consists of two options, the rest is just a wrapper around `greenlock.js` to take LOC from 15 to 5:
 
 * `opts.app` An express app in the format `function (req, res) { ... }` (no `next`).
-* `lex.listen(plainPort, tlsPort)` Accepts port numbers (or arrays of port numbers) to listen on.
+* `glx.listen(plainPort, tlsPort)` Accepts port numbers (or arrays of port numbers) to listen on.
