Has anyone written a line counter with POD sections stripped out?

Here's the somewhat rough-and-ready code I use to count lines in my work application:

#!/usr/bin/perl -w
use strict;
use File::Find;
my($d, $c, $h, $q, $s, $x) = (0, 0, 0, 0, 0, 0);

for my $dir (qw/ cgi lib util /) {
  find(sub { 
    return if /^\.#/ || /,v$/ || /\.(swp|gif|jpg|png|ps|tr|o|a)$/ || /
+~$/ || /^core$/;
    $File::Find::prune = 1, return if $File::Find::dir =~ /\bCVS\b/;
    return unless -f && -T; 
    local *F; 
    my $file = $_; 
    open F, $file or warn "$File::Find::dir/$file: $!\n";

    my $cut = 0;
    my $here = undef;
    my $where;
    while (<F>) {
      if ($cut) {
        ++$$where;
        $cut = 0 if $cut > 0 && /^=cut/;
      } elsif ($here) {
        ++$$where;
        $here = undef if /$here/;
      } elsif (/^=/) {
        ++$d;
        $cut = 1;
        $where = \$d;
      } elsif (!/\S/) {
        ++$s;
      } elsif (/^\s*#/) {
        ++$c;
      } elsif (/<<(?:'(\w+)'|(\w+))/) {
        my $style = $1 || $2;
        $where = ($style eq 'SQL') ? \$q : \$h;
        $here = qr/^$style$/;
        ++$x;
      } elsif (/^__(DATA|END)__$/) {
        $cut = -1;
        $where = \$h;
      } else {
        ++$x;
      }
    }
  }, $dir);
}

print "doc $d, comment $c, SQL $q, text $h, space $s, code $x\n";
