     "@code{pbuilder} is a personal package builder for Debian packages.
@itemize
@item@code{pbuilder} constructs a chroot system, and builds a package inside the
chroot.  It is an ideal system to use to check that a package has correct
build-dependencies.  It uses @code{apt} extensively, and a local mirror, or a
fast connection to a Debian mirror is ideal, but not necessary.
@item@code{pbuilder create} uses debootstrap to create a chroot image.
@item@code{pbuilder update} updates the image to the current state of
testing/unstable/whatever.
@item@code{pbuilder build} takes a @code{*.dsc} file and builds a binary in the
chroot image.
@item@code{pdebuild} is a wrapper for Debian Developers, to allow running
@code{pbuilder} just like @code{debuild}, as a normal user.
