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,

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