21# This file provides the language dependent support in the main Makefile.
22# Each language makefile fragment must provide the following targets:
23#
24# foo.all.build, foo.all.cross, foo.start.encap, foo.rest.encap,
25# foo.info, foo.dvi,
26# foo.install-normal, foo.install-common, foo.install-info, foo.install-man,
27# foo.uninstall, foo.distdir,
28# foo.mostlyclean, foo.clean, foo.distclean, foo.extraclean,
29# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
30#
31# where `foo' is the name of the language.
32#
33# It should also provide rules for:
34#
35# - making any compiler driver (eg: g++)
36# - the compiler proper (eg: cc1plus)
37# - define the names for selecting the language in LANGUAGES.
