package Memoize::ExpireTest;

=head1 NAME

Memoize::ExpireTest - test for Memoize expiration semantics

=head1 DESCRIPTION

This module is just for testing expiration semantics.  It's not a very
good example of how to write an expiration module.

If you are looking for an example, I recommend that you look at the
simple example in the Memoize::Expire documentation, or at the code
for Memoize::Expire itself.

If you have questions, I will be happy to answer them if you send them
to [e-mail].
