Here is a sample makefile (for the handbook) using my proposed
bsd.sgml.mk:

-------------------
SGMLOPTS= -links
.include <bsd.sgml.mk>
-------------------

Simple, eh?

Now, here is the bsd.sgml.mk which I plan to commit if there are
no great objections.  It isn't perfect, but it gets the job done:
