+#
+# This makefile is designed to be run in one of three ways:
+#
+# make clean
+# make depend
+# make build
+# make installsrc
+# This is the most rigorous way to rebuild the source tree.
+# The first two steps will clean the source tree and remake the dependencies.
+# The `make build' will compile and install the libraries and the compiler
+# twice before building the rest of the sources. The `make installsrc' will
+# then install the remaining binaries.
+#
+# make libthenall
+# make installsrc
+# The `make libthenall' will compile and install the libraries, compile
+# and install the compiler and then compile everything else. Note,
+# however, that the libraries will have been built with the old compiler.
+# The `make installsrc' will then install the remaining binaries.
+#
+# make all
+# make install
+# The `make all' (the default) will compile everything, and install
+# nothing. The `make install' will then install everything.
+#
+# C library options: passed to libc makefile.
+# See lib/libc/Makefile for explanation.
+#
+# HOSTLOOKUP must be either named or hosttable.
+# DFLMON must be either mon.o or gmon.o.
+# DEFS may include -DLIBC_SCCS, -DSYSLIBC_SCCS, both, or neither.
+#
+DEFS= -DLIBC_SCCS
+DFLMON= mon.o
+HOSTLOOKUP= named
+LIBCDEFS= HOSTLOOKUP=${HOSTLOOKUP} DFLMON=${DFLMON} DEFS="${DEFS}"
-# Programs that live in subdirectories, and have makefiles of their own.
+# global flags
+# SRC_MFLAGS are used on makes in command source directories,
+# but not in library or compiler directories that will be installed
+# for use in compiling everything else.
