+"""
+    The Pygments reStructuredText directive
+    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+    This fragment is a Docutils_ 0.5 directive that renders source code
+    (to HTML only, currently) via Pygments.
+
+    To use it, adjust the options below and copy the code into a module
+    that you import on initialization.  The code then automatically
+    registers a ``sourcecode`` directive that you can use instead of
+    normal code blocks like this::
+
+        .. sourcecode:: python
+
+            My code goes here.
+
+    If you want to have different code styles, e.g. one with line numbers
+    and one without, add formatters with their names in the VARIANTS dict
+    below.  You can invoke them instead of the DEFAULT one by using a
+    directive option::
+
+        .. sourcecode:: python
+            :linenos:
+
+            My code goes here.
+
+    Look at the `directive documentation`_ to get all the gory details.
+
+    .. _Docutils: https://docutils.sourceforge.io/
