22# This file provides the language dependent support in the main Makefile.
23# Each language makefile fragment must provide the following targets:

25# foo.all.build, foo.all.cross, foo.start.encap, foo.rest.encap,
26# foo.info, foo.dvi,
27# foo.install-normal, foo.install-common, foo.install-info, foo.install-man,
28# foo.uninstall,
29# foo.mostlyclean, foo.clean, foo.distclean, foo.extraclean,
30# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
31#
32# where `foo' is the name of the language.
33#
34# It should also provide rules for:
35#
36# - making any compiler driver (eg: g++)
37# - the compiler proper (eg: cc1plus)
38# - define the names for selecting the language in LANGUAGES.
