How does the fedora brewbuilder work?

[Mark]

Hey,

At this moment i'm looking into using distcc to use another computer
in my network to speed up the compilation progress but while looking
at that stuff i wondered how fedora is doing it. So is the build
system actually a cluster of 10? computers which are working with
distcc to compile all that stuff asap?

Some info about this would be interesting.

Thanx,
Mark.
