=head1 NAME
Log::Log4perl::Filter::LevelRange - Filter for a range of log levels
=head1 SYNOPSIS
log4perl.filter.Match1 = Log::Log4perl::Filter::LevelRange
log4perl.filter.Match1.LevelMin = INFO
log4perl.filter.Match1.LevelMax = ERROR
log4perl.filter.Match1.AcceptOnMatch = true
=head1 DESCRIPTION
This Log4perl custom filter checks if the current message
has a priority matching a predefined range.
The C<LevelMin> and C<LevelMax> parameters define the levels
(choose from C<DEBUG>, C<INFO>, C<WARN>, C<ERROR>, C<FATAL>) marking
the window of allowed messages priorities.
C<LevelMin> defaults to C<DEBUG>, and C<LevelMax> to C<FATAL>.
The additional parameter C<AcceptOnMatch> defines if the filter
is supposed to pass or block the message (C<true> or C<false>).
