=head1 NAME
rolllog - DNSSEC-Tools utility to write messages to the DNSSEC rollover
log file
=head1 SYNOPSIS
rolllog -loglevel <level> <log_message>
=head1 DESCRIPTION
The B<rolllog> program writes log messages to the DNSSEC rollover log file.
B<rolllog> does not actually write the messages itself; rather, it sends them
to the B<rollerd> rollover daemon to write the messages. B<rollerd> keeps
track of a logging level, and only messages of that level or higher are
written to the log file.
=head1 OPTIONS
The following options are recognized:
=over 4
=item B<-loglevel level>
Logging level of this message. The valid levels are defined in
B<rollmgr.pm>(3). This option is required.
=item B<-help>
Display a usage message.
=item B<-Version>
Displays the version information for B<rolllog> and the DNSSEC-Tools package.
