## Usage.
function usage() {
  cat << EOF
Usage: ${0##*/} [options]

Options:  --force       The package will not be built if a package of the same
                        name is already installed, or any of the packages
                        required to build are missing.  This option over-rides
                        these checks and attempts a build anyway.
          --no-cleanup  By default any temporary source, build and package
                        directories will be deleted once the package is built.
                        This option prevents those files from being removed.
          --help        Show this help screen.
