+ * Markdown processing in Javascript done right. We have very particular views
+ * on what constitutes 'right' which include:
+ *
+ * - produces well-formed HTML (this means that em and strong nesting is
+ * important)
+ *
+ * - has an intermediate representation to allow processing of parsed data (We
+ * in fact have two, both as [JsonML]: a markdown tree and an HTML tree).
+ *
+ * - is easily extensible to add new dialects without having to rewrite the
+ * entire parsing mechanics
+ *
+ * - has a good test suite
+ *
+ * This implementation fulfills all of these (except that the test suite could
+ * do with expanding to automatically run all the fixtures from other Markdown
+ * implementations.)
+ *
+ * ##### Intermediate Representation
+ *
+ * *TODO* Talk about this :) Its JsonML, but document the node names we use.
