# This service which allows CGI programs to be provided which do not
# run as the webserver user, but instead are owned by a particular
# other account.
#
# Similar effects can be achieved with Apache's suexec; this facility
# is for administrators who do not trust suexec and wish to defend the
# webserver from the CGI script providers, and vice versa, as much as
# possible. This is achieved by using userv to do the cross-account
# call, rather than a custom setuid helper.
#
# This default configuration allows the webserver user to invoke
# users' CGI programs from each user's ~/public-cgi, but to allow
# external http clients to do this, the webserver will also need to be
# configured.
