+# mozconfigfind - Loads options from .mozconfig onto configure's
+#    command-line. The .mozconfig file is searched for in the 
+#    order:
+#       If $MOZCONFIG is set, use that.
+#       If one of $TOPSRCDIR/.mozconfig or $TOPSRCDIR/mozconfig exists, use it.
+#       If both exist, or if various legacy locations contain a mozconfig, error.
+#       Otherwise, use the default build options.
