+class Markup(unicode):
+    r"""Marks a string as being safe for inclusion in HTML/XML output without
+    needing to be escaped.  This implements the `__html__` interface a couple
+    of frameworks and web applications use.  :class:`Markup` is a direct
+    subclass of `unicode` and provides all the methods of `unicode` just that
+    it escapes arguments passed and always returns `Markup`.
+
+    The `escape` function returns markup objects so that double escaping can't
+    happen.
+
+    The constructor of the :class:`Markup` class can be used for three
+    different things:  When passed an unicode object it's assumed to be safe,
+    when passed an object with an HTML representation (has an `__html__`
+    method) that representation is used, otherwise the object passed is
+    converted into a unicode string and then assumed to be safe:
+
+    >>> Markup("Hello <em>World</em>!")
+    Markup(u'Hello <em>World</em>!')
+    >>> class Foo(object):
+    ...  def __html__(self):
+    ...   return '<a href="#">foo</a>'
+    ... 
+    >>> Markup(Foo())
+    Markup(u'<a href="#">foo</a>')
+
+    If you want object passed being always treated as unsafe you can use the
+    :meth:`escape` classmethod to create a :class:`Markup` object:
+
+    >>> Markup.escape("Hello <em>World</em>!")
+    Markup(u'Hello &lt;em&gt;World&lt;/em&gt;!')
+
+    Operations on a markup string are markup aware which means that all
+    arguments are passed through the :func:`escape` function:
+
+    >>> em = Markup("<em>%s</em>")
+    >>> em % "foo & bar"
+    Markup(u'<em>foo &amp; bar</em>')
+    >>> strong = Markup("<strong>%(text)s</strong>")
+    >>> strong % {'text': '<blink>hacker here</blink>'}
+    Markup(u'<strong>&lt;blink&gt;hacker here&lt;/blink&gt;</strong>')
+    >>> Markup("<em>Hello</em> ") + "<foo>"
+    Markup(u'<em>Hello</em> &lt;foo&gt;')
