The POD should contain enough information for someone using the module to write code that uses it

But this module currently only has me using it. As I said in the question, it is a utility module that will never be published. The reason I am adding POD is to help me remember what what all the methods do without having to keep diving into the source code to look at comments and inspect the code.

We will almost certainly bring on another developer at some point. But even then, I don't expect this module will ever have the same level of POD detail as I would apply to a module that was destined for CPAN.
