checkout w/ removing untracked files

Hi folks,

is there an option to do a checkout _exactly_ as the ref'ed tree ?
(so, also remove untracked files) ?

For my Briegel buildsystem (git://pubgit.metux.de/projects/briegel.git/)
I need to checkout a really tree (iow: no untracked files may be
left in the workdir) from git. ATM I'm removing and recreating the
whole directory first, but I hope to get rid of this step.
