+
+    Usage:

+        html = code.hilite()
+
+    Arguments:
+    * src: Source string or any object with a .readline attribute.
+
+    * lang: String name of Pygments lexer to use for highlighting. Default: `None`.
+
+    * guess_lang: Auto-detect which lexer to use. Ignored if `lang` is set to a valid
+      value. Default: `True`.
+
+    * use_pygments: Pass code to pygments for code highlighting. If `False`, the code is
+      instead wrapped for highlighting by a JavaScript library. Default: `True`.
+
+    * linenums: An alias to Pygments `linenos` formatter option. Default: `None`.
+
+    * css_class: An alias to Pygments `cssclass` formatter option. Default: 'codehilite'.
+
+    * lang_prefix: Prefix prepended to the language when `use_pygments` is `False`.
+      Default: "language-".
+
+    Other Options:
+    Any other options are accepted and passed on to the lexer and formatter. Therefore,
+    valid options include any options which are accepted by the `html` formatter or
+    whichever lexer the code's language uses. Note that most lexers do not have any
+    options. However, a few have very useful options, such as PHP's `startinline` option.

+Python-Markdown Extra Extension
+===============================
+
+A compilation of various Python-Markdown extensions that imitates
+[PHP Markdown Extra](http://michelf.com/projects/php-markdown/extra/).
+
+Note that each of the individual extensions still need to be available
+on your PYTHONPATH. This extension simply wraps them all up as a
+convenience so that only one extension needs to be listed when
+initiating Markdown. See the documentation for each individual
+extension for specifics about that extension.
+
+There may be additional extensions that are distributed with
+Python-Markdown that are not included here in Extra. Those extensions
+are not part of PHP Markdown Extra, and therefore, not part of
+Python-Markdown Extra. If you really would like Extra to include
+additional extensions, we suggest creating your own clone of Extra
+under a different name. You could also edit the `extensions` global
+variable defined below, but be aware that such changes may be lost
+when you upgrade to any future version of Python-Markdown.
+

+Legacy Attributes Extension
+===========================
+
+An extension to Python Markdown which implements legacy attributes.
+
+Prior to Python-Markdown version 3.0, the Markdown class had an `enable_attributes`
+keyword which was on by default and provided for attributes to be defined for elements
+using the format `{@key=value}`. This extension is provided as a replacement for
+backward compatibility. New documents should be authored using attr_lists. However,
+numerious documents exist which have been using the old attribute format for many
+years. This extension can be used to continue to render those documents correctly.
