=head1 OPTIONS

=over 3

=item B<-d | --dir> path

Overides the default directories to check by one directory 'path' and
all its subdirectories.

=item B<-a | --authorsfile>

path from working directory the AUTHORS file.

Redundant as this information could be had from --dir option butI am
feeling too lazy to change the code.

=cut

sub blankline {
    return unless /\.PLS$/ or /\.p[ml]$/ ;
    return unless -e $_;
    my $file = $_;
    open (F, $_) or warn "can't open file $_: $!" && return;
    local $/="";
    while (<F>) {
        print "$file: +|$1|\n" if /[ \t]\n(=[a-z][^\n]+$)/m and $verbose;
        print "$file: ++|$1|\n" if /\w\n(=[a-z][^\n]+$)/m and $verbose;

Show the progress through files during the POD checking.
