+;; This document describes TOML's syntax, using the ABNF format (defined in
+;; RFC 5234 -- https://www.ietf.org/rfc/rfc5234.txt).
+;;
+;; All valid TOML documents will match this description, however certain
+;; invalid documents would need to be rejected as per the semantics described
+;; in the supporting text description.
+
+;; It is possible to try this grammar interactively, using instaparse.
+;; http://instaparse.mojombo.com/
+;;
+;; To do so, in the lower right, click on Options and change `:input-format` to
+;; ':abnf'. Then paste this entire ABNF document into the grammar entry box
+;; (above the options). Then you can type or paste a sample TOML document into
+;; the beige box on the left. Tada!
