# This is just for testing expiration semantics.
# It's not actually 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 mjd-perl/memoize+@plover.com.
