-# This makefile is designed to be run as:
 #	make build
 #	make installsrc
-# The `make build' will compile and install the libraries

-# 
-# It can also be run in the more conventional way:
-#	make
+# 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.  Only `make build' will clean out
+# the source tree as well as remake the dependencies.
+#
+#	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' will compile everything without installing anything.
-# The `make install' will then install everything. Note however
-# that all the binaries will have been loaded with the old libraries.
+# The `make all' (the default) will compile everything, and install
+# nothing.  The `make install' will then install everything.
