+XXX - we exclude extension modules
+
+To include extension modules, first identify them as valid in the

+
+We get functions and classes by parsing the text of .py files.
+Alternatively we could import the modules for discovery, and we'd have
+to do that for extension modules.  This would involve changing the
+``_parse_module`` method to work via import and introspection, and
+might involve changing ``discover_modules`` (which determines which
+files are modules, and therefore which module URIs will be passed to
+``_parse_module``).
+
+NOTE: this is a modified version of a script originally shipped with the
+PyMVPA project, which we've adapted for NIPY use.  PyMVPA is an MIT-licensed
+project."""

+"""
+A directive for including a matplotlib plot in a Sphinx document.
+
+By default, in HTML output, `plot` will include a .png file with a
+link to a high-res .png and .pdf.  In LaTeX output, it will include a
+.pdf.
+
+The source code for the plot may be included in one of three ways:
+
+  1. **A path to a source file** as the argument to the directive::
+
+       .. plot:: path/to/plot.py
+
+     When a path to a source file is given, the content of the
+     directive may optionally contain a caption for the plot::
+
+       .. plot:: path/to/plot.py
+
+          This is the caption for the plot
+
+     Additionally, one my specify the name of a function to call (with
+     no arguments) immediately after importing the module::
+
+       .. plot:: path/to/plot.py plot_function1
+
+  2. Included as **inline content** to the directive::
+
+       .. plot::
+
+          import matplotlib.pyplot as plt
+          import matplotlib.image as mpimg
+          import numpy as np
+          img = mpimg.imread('_static/stinkbug.png')
+          imgplot = plt.imshow(img)
+
+  3. Using **doctest** syntax::
+
+       .. plot::
+          A plotting example:
+          >>> import matplotlib.pyplot as plt
+          >>> plt.plot([1,2,3], [4,5,6])
+
+Options
+-------
+
+The ``plot`` directive supports the following options:
+
+    format : {'python', 'doctest'}
+        Specify the format of the input
+
+    include-source : bool
+        Whether to display the source code. The default can be changed
+        using the `plot_include_source` variable in conf.py
+
+    encoding : str
+        If this source file is in a non-UTF8 or non-ASCII encoding,
+        the encoding must be specified using the `:encoding:` option.
+        The encoding will not be inferred using the ``-*- coding -*-``
+        metacomment.
+
+    context : bool
+        If provided, the code will be run in the context of all
+        previous plot directives for which the `:context:` option was
+        specified.  This only applies to inline code plot directives,
+        not those run from files.
+
+    nofigs : bool
+        If specified, the code block will be run, but no figures will
+        be inserted.  This is usually useful with the ``:context:``
+        option.
+
+Additionally, this directive supports all of the options of the
+`image` directive, except for `target` (since plot will add its own
+target).  These include `alt`, `height`, `width`, `scale`, `align` and
+`class`.
+
+Configuration options
+---------------------
+
+The plot directive has the following configuration options:
+
+    plot_include_source
+        Default value for the include-source option
+
+    plot_pre_code
+        Code that should be executed before each plot.
+
+    plot_basedir
+        Base directory, to which ``plot::`` file names are relative
+        to.  (If None or empty, file names are relative to the
+        directoly where the file containing the directive is.)
+
+    plot_formats
+        File formats to generate. List of tuples or strings::
+
+            [(suffix, dpi), suffix, ...]
+
+        that determine the file format and the DPI. For entries whose
+        DPI was omitted, sensible defaults are chosen.
+
+    plot_html_show_formats
+        Whether to show links to the files in HTML.
+
+    plot_rcparams
+        A dictionary containing any non-standard rcParams that should
+        be applied before each plot.
