# Use "required" for sudo, because we want to use the "trusty" Debian
# distro, which is (currently) only available in the legacy Travis
# infrastructure (i.e., if we put "sudo: false" to use the new container-
# based Travis infrastructure, then "trusty" is not available).  We
# need the "trusty" distro because it has more recent versions of the
# GNU Autotools (i.e., autogen.pl will fail if you use the regular
# distro because the GNU Autotools are too old).
