   3  =head1 NAME
   4  
   5  Memoize::ExpireTest - test for Memoize expiration semantics
   6  
   7  =head1 DESCRIPTION
   8  
   9  This module is just for testing expiration semantics.  It's not a very
  10  good example of how to write an expiration module.
  11  
  12  If you are looking for an example, I recommend that you look at the
  13  simple example in the Memoize::Expire documentation, or at the code
  14  for Memoize::Expire itself.
  15  
  16  If you have questions, I will be happy to answer them if you send them
  17  to mjd-perl-memoize+@plover.com.
