(From the isc.org bind 9 pages)
Some of the programs in the BIND 9 distribution have man pages under the
doc/man directory. In particular, the command line options of "named" are
documented in doc/man/bind/named.8. There is now also a set of man pages
for the lwres library. The man pages are currently not installed
automatically by "make install".
Man pages should be installed if they're available.
Fixed in 9.1.0-2
