  Speed up the next method a little by reducing the number of times it copies its internal
  buffer.  I've also added a script ('rabin.pl') that demonstrates how to use
  Algorithm::RabinKarp with multiple files.  Patches welcome and desired.

  Well, it looks like I messed up the Build.PL file.  Making an incremental release to attempt
  to make it possible to build using the Build.PL, and also reduce the minimum requirements to
  install this module.
