This is a really basic question. A simple / clear answer would help:

What is a handler?

CPAN is full of handlers, but what does a handler do that a subroutine or package method won't do?

When should you use a handler?

Are handler's difficult to write?

Is there a URL or other source about the "a,b,c's" of hanlders (perhaps with examples in PERL code)?

Tnx. McDuff
