(no subject)

I love dictionary.com. It doesn't believe "pumpkins" is a word, but it did give me this:

pumpkin
{jargon} A humourous term for the token - the object
(notional or real) that gives its possessor (the "pumpking" or
the "pumpkineer") exclusive access to something, e.g. applying
patches to a master copy of source (for which the pumpkin
is called a "patch pumpkin").

If anyone could explain any of those words to me I'd be pretty grateful.

Yours,
Pumpking.
