use Algorithm::Hamming::Perl  qw(hamming unhamming unhamming_err);

### Check args
if (@ARGV < 2) {
	die "USAGE: ./example03 infile outfile\n";
}

$infile = $ARGV[0];
$outfile = $ARGV[1];

### Open filehandles
open(IN,"$infile") || die "ERROR: Can't open $infile: $!\n";
open(OUT,">$outfile") || die "ERROR: Can't open $outfile: $!\n";
binmode(IN);
binmode(OUT);

### Use optional faster (but bigger) cache - adds several seconds to startup!
Algorithm::Hamming::Perl::hamming_faster();


### Process data
while (read(IN,$buffer,3072)) {
	$hamcode = hamming($buffer);
	print OUT $hamcode;
}

close IN;
close OUT;
