=head1 NAME

Log::Log4perl::Filter::LevelMatch - Filter to match the log level exactly

=head1 SYNOPSIS

    log4perl.filter.Match1               = Log::Log4perl::Filter::LevelMatch
    log4perl.filter.Match1.LevelToMatch  = ERROR
    log4perl.filter.Match1.AcceptOnMatch = true

=head1 DESCRIPTION

This Log4perl custom filter checks if the currently submitted message
matches a predefined priority, as set in C<LevelToMatch>.
The additional parameter C<AcceptOnMatch> defines if the filter
is supposed to pass or block the message (C<true> or C<false>)
on a match.
