The proxy settings are inserted using cfengine, while the language
settings are inserted using a perl script.  This is the cfengine rules:

   # Enable proxy by default, but drop it on standalone until squid is
    # configured on standalone
    { /etc/environment
      AutoCreate
      AppendIfNoSuchLine "http_proxy=http://webcache:3128";
      AppendIfNoSuchLine "ftp_proxy=http://webcache:3128";
    }

The perl script is in the locale-config-skolelinux package available
from APT source 'deb ftp://ftp.skolelinux.no/skolelinux/ woody local'.
