+TODO(epoger): Launch this (and other unittests within this dir) automatically
+on the housekeeper bot, but first make sure it works properly after having been
+checked out (from both git and svn)
+
+TODO(epoger): Create a command to update the expected results (in
+OUTPUT_DIR_EXPECTATIONS) when appropriate.  For now, you should:
+1. examine the results in OUTPUT_DIR and make sure they are ok
+2. rm -rf OUTPUT_DIR_EXPECTATIONS
+3. mv OUTPUT_DIR OUTPUT_DIR_EXPECTATIONS
+Although, if you're using an SVN checkout, this will blow away .svn directories
+within OUTPUT_DIR_EXPECTATIONS, which wouldn't be good...
