non-english web pages are not build.
This is basically a debug option. Most committers does not touch
the japanese documentation, so they don't need to test the
japanese files.
You can (and are encouraged to) mirror the pages with CVSup.
If you are running apache as installed from the ports collection the
following should make a copy of www.freebsd.org available from
http://wwwN.XX.freebsd.org/. Of course, there are possible
variations on the method...
1) The CVSup file to get the WWW pages
(/usr/local/www/data/freebsd.cvsup in the next step):
www release=current host=cvsup.freebsd.org hostbase=/home base=/usr prefix=/usr/local/www/data/www.freebsd.org delete old use-rel-suffix
2) Add to /etc/crontab
1 5 * * * root /usr/local/bin/cvsup -z -g /usr/local/www/data/freebsd.cvsup
2) Add to /usr/local/etc/apache/access.conf:
