 =head1 BUGS AND LIMITATIONS
 
+The EFA backend is not able to calculate "two-way" routes, i.e. from -> via ->
+to routes with from == to. If from and to are the same stop, it doesn't even
+try to calculate a route ("we recommend walking instead"), if they are close to
+each other it may or may not work.  Workaround: Request from -> via using the
+normal four-argument efa invocation, read the time, use efa -t time via via to
+to to request via -> to.
+
 None known.
