Adding a caption to a plot inserted with the `plot` directive from mpl's
sphinxextensions does not work for me, even though the [documentation][1]
says it should be possible.
The relevant ReST snippet:
```
.. plot:: /home/oliver/git/lcp2/code/python/plot_scripts/tangent_circles.py
:align: center
:alt: 'Schematic drawing of the two solution methods'
Schematic drawing showing the two possible solution methods discussed.
```
I'm getting the following traceback:
# Sphinx version: 1.1.3
# Python version: 2.7.3
# Docutils version: 0.9.1 release
# Jinja2 version: 2.6

RuntimeError: plot:: directive can't have both args and content
I don't see a reference in the documentation saying it's a feature that was
added in a newer version of mpl.
What am I doing wrong?
