5 | Memoize::ExpireTest - test for Memoize expiration semantics
|

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.
|
---|

|
---|
16 | If you have questions, I will be happy to answer them if you send them
|
---|
17 | to [email protected].
