The id value is a slug of + the header text. +* html-classes: Takes a dict mapping html tag names (lowercase) to a + string to use for a "class" tag attribute. Currently only supports + "pre" and "code" tags. Add an issue if you require this for other tags. +* markdown-in-html: Allow the use of `markdown="1"` in a block HTML tag to + have markdown processing be done on its contents. Similar to + but with + some limitations. +* pyshell: Treats unindented Python interactive shell sessions as + blocks. +* link-patterns: Auto-link given regex patterns in text (e.g. bug number + references, revision number references). +* smarty-pants: Replaces ' and " with curly quotation marks or curly + apostrophes. Replaces --, ---, ..., and . . . with en dashes, em dashes, + and ellipses. +* toc: The returned HTML string gets a new "toc_html" attribute which is + a Table of Contents for the document.
