This tool is useful for running makechrootpkg on a remote build server,
and is by default hooked up to send a PKGBUILD and initiate a build on
our shiny new build server "dragon".

v2: script -qfc does not preserve the exit status of the wrapped
command. Add -e so that we can properly abort if makechrootpkg failed.
