+    """Element generator factory.
+
+    Unlike the ordinary Element factory, the E factory allows you to pass in
+    more than just a tag and some optional attributes; you can also pass in
+    text and other elements.  The text is added as either text or tail
+    attributes, and elements are inserted at the right spot.  Some small
+    examples::
+
+        >>> from lxml import etree as ET
+        >>> from lxml.builder import E
+
+        >>> ET.tostring(E("tag"))
+        '<tag/>'
+        >>> ET.tostring(E("tag", "text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E("tag", "text", key="value"))
+        '<tag key="value">text</tag>'
+        >>> ET.tostring(E("tag", E("subtag", "text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    For simple tags, the factory also allows you to write ``E.tag(...)`` instead
+    of ``E('tag', ...)``::
+
+        >>> ET.tostring(E.tag())
+        '<tag/>'
+        >>> ET.tostring(E.tag("text"))
+        '<tag>text</tag>'
+        >>> ET.tostring(E.tag(E.subtag("text"), "tail"))
+        '<tag><subtag>text</subtag>tail</tag>'
+
+    Here's a somewhat larger example; this shows how to generate HTML
+    documents, using a mix of prepared factory functions for inline elements,
+    nested ``E.tag`` calls, and embedded XHTML fragments::
+
+        # some common inline elements
+        A = E.a
+        I = E.i
+        B = E.b
+
+        def CLASS(v):
+            # helper function, 'class' is a reserved word
+            return {'class': v}
+
+        page = (
+            E.html(
+                E.head(
+                    E.title("This is a sample document")
+                ),
+                E.body(
+                    E.h1("Hello!", CLASS("title")),
+                    E.p("This is a paragraph with ", B("bold"), " text in it!"),
+                    E.p("This is another paragraph, with a ",
+                        A("link", href="http://www.python.org"), "."),
+                    E.p("Here are some reserved characters: <spam&egg>."),
+                    ET.XML("<p>And finally, here is an embedded XHTML fragment.</p>"),
+                )
+            )
+        )
+
+        print ET.tostring(page)
+
+    Here's a prettyprinted version of the output from the above script::
+
+        <html>
+          <head>
+            <title>This is a sample document</title>
+          </head>
+          <body>
+            <h1 class="title">Hello!</h1>
+            <p>This is a paragraph with <b>bold</b> text in it!</p>
+            <p>This is another paragraph, with <a href="http://www.python.org">link</a>.</p>
+            <p>Here are some reserved characters: &lt;spam&amp;egg&gt;.</p>
+            <p>And finally, here is an embedded XHTML fragment.</p>
+          </body>
+        </html>
+
+    For namespace support, you can pass a namespace map (``nsmap``)
+    and/or a specific target ``namespace`` to the ElementMaker class::
+
+        >>> E = ElementMaker(namespace="http://my.ns/")
+        >>> print(ET.tostring( E.test ))
+        <test xmlns="http://my.ns/"/>
+
+        >>> E = ElementMaker(namespace="http://my.ns/", nsmap={'p':'http://my.ns/'})

+lxml-based doctest output comparison.
+
+Note: normally, you should just import the `lxml.usedoctest` and
+`lxml.html.usedoctest` modules from within a doctest, instead of this
+one::
+
+    >>> import lxml.usedoctest # for XML output
+
+    >>> import lxml.html.usedoctest # for HTML output
+
+To use this module directly, you must call ``lxmldoctest.install()``,
+which will cause doctest to use this in all subsequent calls.
+
+This changes the way output is checked and comparisons are made for
+XML or HTML-like content.
+
+XML or HTML content is noticed because the example starts with ``<``
+(it's HTML if it starts with ``<html``).  You can also use the
+``PARSE_HTML`` and ``PARSE_XML`` flags to force parsing.
+
+Some rough wildcard-like things are allowed.  Whitespace is generally
+ignored (except in attributes).  In text (attributes and text in the
+body) you can use ``...`` as a wildcard.  In an example it also
+matches any trailing tags in the element, though it does not match
+leading tags.  You may create a tag ``<any>`` or include an ``any``
+attribute in the tag.  An ``any`` tag matches any tag, while the
+attribute matches any and all attributes.
+
+When a match fails, the reformatted example and gotten text is
+displayed (indented), and a rough diff-like output is given.  Anything
+marked with ``+`` is in the output but wasn't supposed to be, and
+similarly ``-`` means its in the example but wasn't in the output.
+
+You can disable parsing on one line with ``# doctest:+NOPARSE_MARKUP``

+class Cleaner(object):
+    """
+    Instances cleans the document of each of the possible offending
+    elements.  The cleaning is controlled by attributes; you can
+    override attributes in a subclass, or set them in the constructor.
+
+    ``scripts``:
+        Removes any ``<script>`` tags.
+
+    ``javascript``:
+        Removes any Javascript, like an ``onclick`` attribute. Also removes stylesheets
+        as they could contain Javascript.
+
+    ``comments``:
+        Removes any comments.
+
+    ``style``:
+        Removes any style tags.
+
+    ``inline_style``
+        Removes any style attributes.  Defaults to the value of the ``style`` option.
+
+    ``links``:
+        Removes any ``<link>`` tags
+
+    ``meta``:
+        Removes any ``<meta>`` tags
+
+    ``page_structure``:
+        Structural parts of a page: ``<head>``, ``<html>``, ``<title>``.
+
+    ``processing_instructions``:
+        Removes any processing instructions.
+
+    ``embedded``:
+        Removes any embedded objects (flash, iframes)
+
+    ``frames``:
+        Removes any frame-related tags
+
+    ``forms``:
+        Removes any form tags
+
+    ``annoying_tags``:
+        Tags that aren't *wrong*, but are annoying.  ``<blink>`` and ``<marquee>``
+
+    ``remove_tags``:
+        A list of tags to remove.  Only the tags will be removed,
+        their content will get pulled up into the parent tag.
+
+    ``kill_tags``:
+        A list of tags to kill.  Killing also removes the tag's content,
+        i.e. the whole subtree, not just the tag itself.
+
+    ``allow_tags``:
+        A list of tags to include (default include all).
+
+    ``remove_unknown_tags``:
+        Remove any tags that aren't standard parts of HTML.
+
+    ``safe_attrs_only``:
+        If true, only include 'safe' attributes (specifically the list
+        from the feedparser HTML sanitisation web site).
+
+    ``safe_attrs``:
+        A set of attribute names to override the default list of attributes
+        considered 'safe' (when safe_attrs_only=True).
+
+    ``add_nofollow``:
+        If true, then any <a> tags will have ``rel="nofollow"`` added to them.
+
+    ``host_whitelist``:
+        A list or set of hosts that you can use for embedded content
+        (for content like ``<object>``, ``<link rel="stylesheet">``, etc).
+        You can also implement/override the method
+        ``allow_embedded_url(el, url)`` or ``allow_element(el)`` to
+        implement more complex rules for what can be embedded.
+        Anything that passes this test will be shown, regardless of
+        the value of (for instance) ``embedded``.
+
+        Note that this parameter might not work as intended if you do not
+        make the links absolute before doing the cleaning.
+
+        Note that you may also need to set ``whitelist_tags``.
+
+    ``whitelist_tags``:
+        A set of tags that can be included with ``host_whitelist``.
+        The default is ``iframe`` and ``embed``; you may wish to
+        include other tags like ``script``, or you may want to
+        implement ``allow_embedded_url`` for more control.  Set to None to
+        include all tags.
