## What is the 'Forking Lemma' (in reguards to cryptography) ?

I want to know what the forking lemma is in simple terms. I've read a few academic papers which attempt to describe the lemma yet they are always too complex and sometimes vague. Maybe a step by step outline of the lemma would suffice. Also it may help to describe the splitting lemma also.
