-Matplotlib in a web application server
-====================================================
-
-Many users report initial problems trying to use maptlotlib in web
-application servers, because by default matplotlib ships configured to
-work with a graphical user interface which may require an X11
-connection. Since many barebones application servers do not have X11
-enabled, you may get errors if you don't configure matplotlib for use
-in these environments. Most importantly, you need to decide what
-kinds of images you want to generate (PNG, PDF, SVG) and configure the
-appropriate default backend. For 99% of users, this will be the Agg
-backend, which uses the C++ `antigrain <http://antigrain.com>`_
-rendering engine to make nice PNGs. The Agg backend is also
-configured to recognize requests to generate other output formats
-(PDF, PS, EPS, SVG). The easiest way to configure matplotlib to use
-Agg is to call::
-
- # do this before importing pylab or pyplot
- import matplotlib
- matplotlib.use('Agg')
- import matplotlib.pyplot as plt
-
-For more on configuring your backend, see
-:ref:`what-is-a-backend`.
-
-Alternatively, you can avoid pylab/pyplot altogeher, which will give
-you a little more control, by calling the API directly as shown in
-`agg_oo.py <http://matplotlib.sf.net/examples/api/agg_oo.py>`_ .
-
-You can either generate hardcopy on the filesystem by calling savefig::
-
- # do this before importing pylab or pyplot
- import matplotlib
- matplotlib.use('Agg')
- import matplotlib.pyplot as plt
- fig = plt.figure()
- ax = fig.add_subplot(111)

-.. _how-to-submit-patch:
-
-Submit a patch
-========================
-
-First obtain a copy of matplotlib svn (see :ref:`install-svn`) and
-make your changes to the matplotlib source code or documentation and
-apply a `svn diff`. If it is feasible, do your diff from the top
-level directory, the one that contains :file:`setup.py`. Eg,::
-
- > cd /path/to/matplotlib/source
- > svn diff > mypatch.diff
-
-and then post your patch to the `matplotlib-devel
-<http://sourceforge.net/mail/?group_id=80706>`_ mailing list. If you
-do not get a response within 24 hours, post your patch to the
-sourceforge patch `tracker
-<http://sourceforge.net/tracker2/?atid=560722&group_id=80706&func=browse>`_,
-and follow up on the mailing list with a link to the sourceforge patch
-submissions. If you still do not hear anything within a week (this
-shouldn't happen!), send us a kind and gentle reminder on the mailing
-list.
-
-If you have made lots of local changes and do not want to a diff
-against the entire tree, but rather against a single directory or
-file, that is fine, but we do prefer svn diffs against HEAD.
-
-You should check out the guide to developing matplotlib to make sure
-your patch abides by our coding conventions
-:ref:`developers-guide-index`.
-
-
-.. _how-to-contribute-docs:
-
-Contribute to matplotlib documentation
-=========================================
-
-matplotlib is a big library, which is used in many ways, and the
-documentation we have only scratches the surface of everything it can
-do. So far, the place most people have learned all these features are
-through studying the examples (:ref:`how-to-search-examples`), which is a
-recommended and great way to learn, but it would be nice to have more
-official narrative documentation guiding people through all the dark
-corners. This is where you come in.
-
-There is a good chance you know more about matplotlib usage in some
-areas, the stuff you do every day, than any of the developers. *Just
-pulled your hair out compiling matplotlib for windows?* Write a FAQ or
-a section for the :ref:`installing` page. *Are you a digital signal
-processing wizard?* Write a tutorial on the signal analysis plotting
-functions like :func:`~matplotlib.pyplot.xcorr`,
-:func:`~matplotlib.pyplot.psd` and
-:func:`~matplotlib.pyplot.specgram`. *Do you use matplotlib with
-`django <ttp://www.djangoproject.com/>`_ or other popular web
-application servers?* Write a FAQ or tutorial and we'll find a place
-for it in the :ref:`users-guide-index`. *Bundle matplotlib in a `py2exe
-<http://www.py2exe.org/>`_ app?* ... I think you get the idea.
-
-matplotlib is documented using the `sphinx
-<http://sphinx.pocoo.org/index.html>`_ extensions to restructured text
-`ReST <http://docutils.sourceforge.net/rst.html>`_. sphinx is a
-extensible python framework for documentation projects which generates
-HTML and PDF, and is pretty easy to write; you can see the source for this
-document or any page on this site by clicking on *Show Source* link
-at the end of the page in the sidebar (or `here
-<../_sources/faq/howto_faq.txt>`_ for this document).
-
-The sphinx website is a good resource for learning sphinx, but we have
-put together a cheat-sheet at :ref:`documenting-matplotlib` which
-shows you how to get started, and outlines the matplotlib conventions
-and extensions, eg for including plots directly from external code in
-your documents.
-
-Once your documentation contributions are working (and hopefully
-tested by actually *building* the docs) you can submit them as a patch
-against svn. See :ref:`install-svn` and :ref:`how-to-submit-patch`.

-.. _how-to-search-examples:
-
-Search examples
-=========================================
-
-The nearly 300 code :ref:`examples-index` included with the matplotlib
-source distribution are full-text searchable from the :ref:`search`
-page, but sometimes when you search, you get a lot of results from the
-:ref:`api-index` or other documentation that you may not be interested in if
-you just want to find a complete, free-standing, working piece of
-example code. To facilitate example searches, we have tagged every
-page with the keyword ``codex`` for *code example* which shouldn't
-appear anywhere else on this site except in the FAQ and in every
-example. So if you want to search for an example that uses an ellipse,
