=head1 NAME
aseag-m - Unofficial interface to the ASEAG departure monitor
=head1 SYNOPSIS
B<aseag-m> [B<-abfprV>] [B<-l> I<lines>] [B<-s> I<timefmt> | B<-S> I<timefmt>]
[B<-v> I<stopname>] I<stopname>
=head1 VERSION
version 0.04
=head1 DESCRIPTION
B<aseag-m> lists upcoming bus departures at the ASEAG stop I<name>.
=head1 OPTIONS
=over
=item B<-a>, B<--route-after>
For each departure, include the route leading to I<name>. Both stop names and
departure times are shown.
=item B<-b>, B<--route-before>
For each departure, include the route after I<name>. Both stop names and
departure times are shown.
=item B<-f>, B<--full-route>
For each departure, include the entire route (stop names and departure times).
=item B<-l>, B<--line> I<lines>
Limit output to departures of I<lines> (comma-separated list of line
names, may be used multiple times).
=item B<-p>, B<--with-past>
Include past departures. Applies both to the departure output and to the
route output of B<-a>, B<-b>, B<-f>.
=item B<-r>, B<--relative>
Show relative times. Appleas both to departure and route output.
=item B<-s>, B<--strftime> I<format>
Format absolute times in I<format>, applies both to departure and route
output. See DateTime(3pm) for allowed patterns.
=item B<-S>, B<--strfrel> I<format>
Format relative times in I<format>, only applies when used with B<-r>.
See DateTime::Format::Duration(3pm) for allowed patterns.
=item B<-v>, B<--via> I<stop>
Only show lines which will also service I<stop> after I<name>. With B<-b>,
I<stop> must be in the schedule before I<name>, with B<-f> it may be anywhere,
with B<-a> (and by default) it must be after I<name>.
=item B<-V>, B<--version>
Show version information.
=back
=head1 EXIT STATUS
Normally zero. B<1> means B<aseag-m> was called with invalid options,
B<2> indicates a request error from Travel::Status::DE::URA(3pm),
B<3> a bad (unknown or ambiguous) I<stop> name.
=head1 CONFIGURATION
None.
