Hi guys,
I created this little library initially for a mod that showed dynamic information on a formspec, but has since been used in many other little projects.
This is exactly what it says in the title. it is a way of caching information for use in your scripts, It is not file based and only stores the cached data in a table, the data is then removed after a predefined expiry time.
Find it on Git Hub, Feel free to contribute anything you feel would improve it:
