NAME
       oddtrans - complement translation tables for Oddmuse

SYNOPSIS
       oddtrans [OPTIONS]... [FILE]...

DESCRIPTION

       Read all the calls to T(), Ts(), and Tss() from all FILEs, and print
       them on standard output, followed by their translation (usually the
       empty string unless you use -l to load a library).

       -l
              load a library from a previous run; you can use multiple -l

EXAMPLES

       oddtrans -l german-utf8.pl wiki.pl modules/*.pl > new-german-utf8.pl

};

$arg = shift;
while ($arg =~ /^-l/) {
  $file = substr($arg, 3);
  $file = shift unless $file;
  die $help unless -f $file;
  %backup = %Translate;
  do $file or die "Cannot do $file";
  foreach $key (keys %Translate) {
    $backup{$key} = $Translate{$key};
  }
  %Translate = %backup;
  $arg = shift;
}
unshift(@ARGV,$arg); # shove the last one back because it is not -l!

  $result = $Translate{$string}  if (defined($Translate{$string}));
  return ' '  if ($seen{$string});
  $seen{$string} = 1;
  print $string . "\n" . $result . "\n";
  return ' ';
