	We have a utility here which reads the instructions for compiling
	a program directly out of the source itself....

	We are thinking of replacing /usr/src/cmd/MAKE with this mechanism.

Before you do that, think about people who use makefiles to make
other things: nroff output, other languages, etc.  I have used the
following makefile occasionally:

 .SUFFIXES: .nr .out .xer
 .nr.out:
	nroff -me -Tlpr $< >$@
 .nr.xer:
	nroff -me -Tx12-8 $< | xer -p12 -l8 >/dev/tty17

Somehow I don't think you can express that with your setup.  If you have
the commands in the C comments, nroff prints them.  Nroff comments look
like

 .\"

(I think).  In any case they are very different from any other type
of comment I've ever seen.
