document accessibility options

Set your walking speed to I<speed>.

Accepted values: normal (default), fast, slow

=item B<-x>|B<--accessibility> I<types>

Request connections satisfying all of the specified accessibility I<types>

(comma-separated list, option may be repeated). Please note that this may cause

the backend to return no results at all, either because no such connection

exists or because the required lines do not have the correct accessibility

attributes set.

The following I<types> are supported:

=over

=item e / no-escalators

Transfers must be possible without taking an escalator.

=item E / no-elevators

Transferst must be possible without using an elevator.

=item i / info

Does not restrict the requested connections. However, this option causes

B<efa> to display additional accessibility information for each route part

(where available). When B<-x w> or B<-x l> do not return any connections,

using B<-x i> might be more helpful (though it cannot guarantee that any of

the results satisfy the respective type).

=item l / nf / low-platform

All vehicles must be low-platform ("Niederflur").

=item s / no-stairs

Transfers must be possible without stairs (e.g. via escalators/elevators or

ramps).

=item w / wheelchair

All vehicles must be wheelchair accessible.
