Remove original license disclaimer.

Add Caldera license.

Approved by:    David Taylor <davidt@caldera.com>

Make roughly buildable under FreeBSD.

The results are not perfect: the original Makefile referred to a refer
file papers/Ind, which doesn't seem to have been kept, so the
references to other publications are missing.  In addition, the
pagination is not correct, with the result that some .DS/.DE blocks
leave large amounts of white space empty before them.  Possibly this
could be fixed by putting the (blank) footnotes at the end.
