# It is strongly recommended to not run Privoxy as root. You should
# configure/install/run Privoxy as an unprivileged user, preferably by creating a
# "privoxy" user and group just for this purpose. See your local documentation
# for the correct command line to do add new users and groups (something like
# adduser, but the command syntax may vary from platform to platform).
#
# /etc/passwd might then look like:
#
#   privoxy:*:7777:7777:privoxy proxy:/no/home:/no/shell
#
#
# And then /etc/group, like:
#
#   privoxy:*:7777:
