23# foo.all.cross, foo.start.encap, foo.rest.encap,
24# foo.install-common, foo.install-man, foo.install-info, foo.install-pdf,
25# foo.install-html, foo.info, foo.dvi, foo.pdf, foo.html, foo.uninstall,
26# foo.mostlyclean, foo.clean, foo.distclean,
27# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
28#
29# where `foo' is the name of the language.
30#
31# It should also provide rules for:
32#
33# - making any compiler driver (eg: gcc)
34# - the compiler proper (eg: cc1)
35# - define the names for selecting the language in LANGUAGES.
