#    Alternatively it may contain the path to a normal file and the URLs will
#    be taken from that.  Or the style may contain the URLs as its values.
#
#  local
#    Specify a local web server as an array with three elements:
#      <hostname> <doc root> <user area>
#    where hostname is the name of the web server, doc root is the path to
#    the default web pages for the server and user area is the directory
#    name used by a user placing web pages within their home area.
