# foo.all.build, foo.all.cross, foo.start.encap, foo.rest.encap,
# foo.info, foo.dvi,
# foo.install-normal, foo.install-common, foo.install-info, foo.install-man,

# foo.mostlyclean, foo.clean, foo.distclean, foo.extraclean,
# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
#
# where `foo' is the name of the language.
#
# It should also provide rules for:
#
# - making any compiler driver (eg: g++)
# - the compiler proper (eg: cc1plus)
# - define the names for selecting the language in LANGUAGES.
