A number of the broken links in the iostreams docs are supposed to point to the document at http://www.boost.org/doc/html/CopyConstructible.html. I used a relative path so that users without full time web access would be directed to their own hard drives. I've verified that (at least some of) these relative links are correct, under the assumption that the document $(BOOST_ROOT)/doc/html/CopyConstructible.html will be present in the distribution.
The broken links for date_time also point to a file in the $(BOOST_ROOT)/doc/html directory. I've verified these links will work as long as $(BOOST_ROOT)/doc/html/date_time.html will be present in the distribution. The min/max violations for date_time are not violations. They appear in comments. We are addressing the remaining date_time issues. Bart
