I'm not sure if this belongs under Math:: or Algorithms:: or something. It is writtin, it's just waiting on your words. I just export is_mdiff(). I'm still reading the FAQ on contrib... __END__ # Below is the stub of documentation for your module. You better edit it! =head1 NAME ???::MDiff - Perl extension for m-differece detection. =head1 SYNOPSIS use ???::MDiff; =head1 DESCRIPTION m-difference is a comparason I designed myself. Two strings are m-different if at least m of the characters in the strings differ... that is, if m=3, then there are at least 3 indicies (i, j, k) such that str1[i] != str2[i], str1[j] != str2[j] and str1[k] != str2[k]. =head1 Exported constants is_mdiff($m, $str1, $str2); =head1 AUTHOR Jettero Heller <[EMAIL PROTECTED]> =head1 SEE ALSO perl(1). =cut -- http://www.voltar.org/
