$0 usage:

options:

--recordings [number of recordings]

    Outputs information on the next [number of recordings] shows to be recorded
    by MythTV and that match the criteria specified for --scheduled,
    --duplicates, --deactivated, and --conflicts.  To output information on all
    matching recordings, specify -1.

    default:  $dnum_recordings

--hours [number of hours]

    Outputs information on recordings starting in the next [number of hours]
    and that match the criteria specified for --scheduled, --duplicates,
    --deactivated, and --conflicts.  This option may be specified in
    conjunction with --minutes and --seconds.  To output information on all
    matching recordings regardless of start time, specify -1 for --hours,
    --minutes, and --seconds.

    default:  $dhours

--minutes [number of minutes]

    Outputs information on recordings starting in the next [number of minutes]
    and that match the criteria specified for --scheduled, --duplicates,
    --deactivated, and --conflicts.  This option may be specified in
    conjunction with --hours and --seconds.  To output information on all
    matching recordings regardless of start time, specify -1 for --hours,
    --minutes, and --seconds.

    default:  $dminutes

--seconds [number of seconds]

    Outputs information on recordings starting in the next [number of seconds]
    and that match the criteria specified for --scheduled, --duplicates,
    --deactivated, and --conflicts.  This option may be specified in
    conjunction with --hours and --minutes.  To output information on all
    matching recordings regardless of start time, specify -1 for --hours,
    --minutes, and --seconds.

    default:  $dseconds

--show_scheduled|--no_show_scheduled

    Outputs information about scheduled recordings.  Scheduled recordings are
    those that MythTV plans to actually record.

    default:  $dscheduled

--show_duplicates|--no_show_duplicates

    Outputs information about duplicate recordings.  Duplicate recordings are
    those that will not be recorded because of the specified duplicate matching
    policy for the rule.

    default:  $dduplicates

--show_deactivated|--no_show_deactivated

    Outputs information about deactivated recordings.  Deactivated recordings
    are those that MythTV will not record because the schedule is inactive,
    because the showing was set to never record, because the show is being
    recorded in an earlier or later showing, because there are too many
    recordings or not enough disk space to allow the recording, or because
    the show you\'ve specified for recording is not listed in the timeslot
    specified.

    default:  $ddeactivated

--show_conflicts|--no_show_conflicts

    Outputs information about conflicts (those shows that MythTV cannot record
    because of other higher-priority scheduled recordings).

    default:  $dconflicts

--heading [heading]
    Output the [heading] before printing information about recordings.

    default:  \'$dheading\'

--plain_text
    Output information in plain text format (i.e. for inclusion in an e-mail
    notification).

--text_format [format]
    Use the provided [format] to display information on the recordings.  The
    format should use the same format specifiers used by mythlink.pl, but
    may also use \\r and/or \\n for line breaks and %rs for recording status.
    This option is ignored if --plain_text is not used.

    default:  \'$dtext_format\'

--no_conflicts_message [message]
    Use the provided [message] to specify there are no conflicts.  This option
    is used when only information about conflicts is requested and there are
    no conflicts.  I.e. it is only used with the combination of show_*
    options --show_conflicts, --no_show_scheduled, --no_show_deactivated,
    and --no_show_duplicates .

    default:  \'$dno_conflicts_message\'

--help

    Show this help text.
