+Reads configuration information from Start by parsing /etc/sa.conf,
+then the contents of ~/sa.d/ which match ^[\w\d][\w\d_.-]+$
+
+The configuration file contains a list of svn repositories which
+should be queried; each line can contain a tab, which indicates that
+the command following the tab should be run after the svn directory is
+updated.
+
+The configuration files are read in the order given above.
