Last night's scribbles:

- Revise abstract based on Guido's comments from way back.
- Point out that LaTeX is a structured system & we're using it that
  way.
- Add a small section on marking up code examples.

+  \subsection{Showing Code Examples}
+
+    Examples of Python source code or interactive sessions are
+    represented as \env{verbatim} environments.  This environment
+    is a standard part of \LaTeX{}.  It is important to only use
+    spaces for indentation in code examples since \TeX{} drops tabs
+    instead of converting them to spaces.
+
+    Representing an interactive session requires including the prompts
+    and output along with the Python code.  No special markup is
+    required for interactive sessions.
+
+    Within the \env{verbatim} environment, characters special to
+    \LaTeX{} do not need to be specially marked in any way.  The entire
+    example will be presented in a monospaced font; no attempt at
+    ``pretty-printing'' is made, as the environment must work for
+    non-Python code and non-code displays.
+
+    The Python Documentation Special Interest Group has discussed a
+    number of approaches to creating pretty-printed code displays and
+    interactive sessions; see the Doc-SIG area on the Python Web site
+    for more information on this topic.
