 OPTIONS
 -------
 
+You may specify *tren* options in one of three ways:
+
+  1) On the command line
+  2) In an "include" file specified with ``-I filename`` on the command line
+  3) Via the ``$TREN`` environment variable
+
+Note that options specified on the command line are evaluated from
+left to right and supercede any options specified in the environment
+variable.  Think of any options set in ``$TREN`` as the "leftmost
+command line options".

   -1   Rename only the first instance of the specified string
