I am designing a module set that I may want to some day be published on CPAN. It will contain components that I know would need to be overridden if used elsewhere, such as logging or database access. I would like for someone to be able to create their overriding logging class, use it and then use my class. My class would then use the overridden class instead of my own.

How do I do this or advise the overriding class to be written? Are there standard references that say how to do this? Are there standard modules that would help with this? Do I need to write an AUTOLOAD method?
