Apache Manual settings on FreeBSD

在FreeBSD设置Apache手册：
在httpd.conf后面加入下面的设置：
# This should be changed to the ServerRoot/manual/.  The alias provides
# the manual, even if you choose to move your DocumentRoot.  You may comment
# this out if you do not care for the documentation.
#
AliasMatch ^/manual(?:/(?:de|en|fr|ja|ko|ru))?(/.*)?$ "/usr/local/share/doc/apache22$1" ##和上面的是同一行
