Why do beans produce flatulence?

As the poet said,

"Beans, beans, good for the heart.
 The more you eat, the more you fart."

It certainly seems to be true in my case  [:I], although I'm not sure about about the heart bit.

Anyway, why is that, and why does it seem to effect some people more than others, or are they really just building up pressure?
There ain'ta no sanity clause, and there ain'ta no centrifugal force Šther.

Variations in gut flora* in different individuals: (* the microorganisms which call your colon home).

A further result is flatulence, specifically the metabolism of oligosaccharides (notably from beans) by Methanobrevibacter smithii.
