 =head1 DESCRIPTION
 
-B<efa-m> lists scheduled tram, bus and train departures at the location I<name>
-in I<city>.  Realtime data (i.e. delays) is included if available, it's
-visible in the output as a "+x" remark (meaning a delay of x minutes).
+B<efa-m> lists scheduled tram, bus and train departures at the location I<name>.
+If I<city> is specified, I<name> refers to a location within I<city>. Otherwise,
+I<name> must be self-contained. I.e., both C<< efa Essen Hbf >> and
+C<< efa "Essen Hbf" >> are valid. Note, however, than C<< efa E Hbf >> works,
+but C<< efa "E Hbf" >> does not.
 
 By default, I<name> refers to a stop, this can be changed by specifying
 I<type>.  Supported types are B<address> and B<poi> (point of interest).
