The title sums it up. Good ol' Perl text processing, plus awesome new list processing (will be useful for n-grams, etc.). My favorite is slide #85, though. Communication with other processes in Perl 5 is always a huge pain, and I can never get it to not hang; you have to unbuffer STDOUT via $|++, then you have to read from STDIN and maybe STDERR to keep it from blocking.
