based distributions (like Trisquel) through HTTP.  It also has partial support
for HTTPS and other distributions / repositories (OpenSUSE, Arch Linux,
Sourceforge mirror network, Cygwin mirrors) as this requires more
configuration and comes with some limitations.  Packages can be imported
manually either by copying files from another apt-cacher-ng instance or by
importing them from CD, DVD, jigdo, etc.  While apt-cacher-ng can work offline,
it requires some online access before that to build valid index files.  It also
supports partial mirroring.  It can be configured through configuration files
and/or a web interface and/or a command line tool.")

     "@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.
