From 327be06f9e1741abb188bc1aa0df8a619972734b Mon Sep 17 00:00:00 2001
From: John MacFarlane <jgm@berkeley.edu>
Date: Sun, 28 Dec 2014 20:28:11 -0800
Subject: Removed old 'ast' format, now that we have 'xml'.

The xml representation of the AST is not quite as pretty, but
it contains the same information and is not in an ad hoc format.

See #53.
