+
+    Usage:
+        code = CodeHilite(src=some_code, lang='python')
+        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.
+    Any invalid options are ignored without error.

+A compilation of various Python-Markdown extensions that imitates

+
+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

+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.

+
+INLINE PATTERNS
+=============================================================================
+
+Inline patterns such as *emphasis* are handled by means of auxiliary
+objects, one per pattern.  Pattern objects must be instances of classes
+that extend markdown.Pattern.  Each pattern object uses a single regular
+expression and needs support the following methods:
+
+    pattern.getCompiledRegExp() # returns a regular expression
+
+    pattern.handleMatch(m) # takes a match object and returns
+                           # an ElementTree element or just plain text
+
+All of python markdown's built-in patterns subclass from Pattern,
+but you can add additional patterns that don't.
+
+Also note that all the regular expressions used by inline must
+capture the whole block.  For this reason, they all start with
+'^(.*)' and end with '(.*)!'.  In case with built-in expression
+Pattern takes care of adding the "^(.*)" and "(.*)!".
+
+Finally, the order in which regular expressions are applied is very
+important - e.g. if we first replace http://.../ links with <a> tags
+and _then_ try to replace inline html, we would end up with a mess.
+So, we apply the expressions in the following order:
+
+* escape and backticks have to go before everything else, so
+  that we can preempt any markdown patterns by escaping them.
+
+* then we handle auto-links (must be done before inline html)
+
+* then we handle inline HTML.  At this point we will simply
+  replace all inline HTML strings with a placeholder and add
+  the actual HTML to a hash.
+
+* then inline images (must be done before links)
+
+* then bracketed links, first regular then reference-style
+
+* finally we apply strong and emphasis

+    Get the version (PEP 440).
+
+    A biased approach to the PEP 440 semantic version.
+
+    Provides a tuple structure which is sorted for comparisons `v1 > v2` etc.
+      (major, minor, micro, release type, pre-release build, post-release build, development release build)
+    Release types are named in is such a way they are comparable with ease.
+    Accessors to check if a development, pre-release, or post-release build. Also provides accessor to get
+    development status for setup files.
+
+    How it works (currently):
+
+    - You must specify a release type as either `final`, `alpha`, `beta`, or `candidate`.
+    - To define a development release, you can use either `.dev`, `.dev-alpha`, `.dev-beta`, or `.dev-candidate`.
+      The dot is used to ensure all development specifiers are sorted before `alpha`.
+      You can specify a `dev` number for development builds, but do not have to as implicit development releases
+      are allowed.
+    - You must specify a `pre` value greater than zero if using a prerelease as this project (not PEP 440) does not
+      allow implicit prereleases.
+    - You can optionally set `post` to a value greater than zero to make the build a post release. While post releases
+      are technically allowed in prereleases, it is strongly discouraged, so we are rejecting them. It should be
+      noted that we do not allow `post0` even though PEP 440 does not restrict this. This project specifically
+      does not allow implicit post releases.
+    - It should be noted that we do not support epochs `1!` or local versions `+some-custom.version-1`.
+
+    Acceptable version releases:
+
+    ```
+    Version(1, 0, 0, "final")                    1.0
+    Version(1, 2, 0, "final")                    1.2

+    A `Registry` instance provides two public methods to alter the data of the
+    registry: `register` and `deregister`. Use `register` to add items and
+    `deregister` to remove items. See each method for specifics.
+
+    When registering an item, a "name" and a "priority" must be provided. All
+    items are automatically sorted by "priority" from highest to lowest. The
+    "name" is used to remove ("deregister") and get items.
+
+    A `Registry` instance it like a list (which maintains order) when reading
+    data. You may iterate over the items, get an item and get a count (length)
+    of all items. You may also check that the registry contains an item.
+
+    When getting an item you may use either the index of the item or the
+    string-based "name". For example:
+
+        registry = Registry()
+        registry.register(SomeItem(), 'itemname', 20)
+        # Get the item by index
+        item = registry[0]
+        # Get the item by name
+        item = registry['itemname']
+
+    When checking that the registry contains an item, you may use either the
+    string-based "name", or a reference to the actual item. For example:
+
+        someitem = SomeItem()
+        registry.register(someitem, 'itemname', 20)

+        assert 'itemname' in registry

+// Acorn: Loose parser
+//
+// This module provides an alternative parser (`parse_dammit`) that
+// exposes that same interface as `parse`, but will try to parse
+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make
+// invasive changes and simplifications without creating a complicated
+// tangle.
