-Adding animations
------------------
-
-Animations are scraped automatically by Sphinx-gallery. If this is not
-desired,
-there is also a Matplotlib Google/Gmail account with username ``mplgithub``
-which was used to setup the github account but can be used for other
-purposes, like hosting Google docs or Youtube videos.  You can embed a
-Matplotlib animation in the docs by first saving the animation as a
-movie using :meth:`matplotlib.animation.Animation.save`, and then
-uploading to `Matplotlib's Youtube
-channel <https://www.youtube.com/user/matplotlib>`_ and inserting the
-embedding string youtube provides like:

-An example save command to generate a movie looks like this
-
-.. code-block:: python
-
-    ani = animation.FuncAnimation(fig, animate, np.arange(1, len(y)),
-        interval=25, blit=True, init_func=init)
-
-    ani.save('double_pendulum.mp4', fps=15)
