# NewsPro User CGI
# Version: 3.7.4 build 23
# See newspro.cgi for license information.
# SCRIPT SETTINGS
# If you are using Microsoft IIS, set the following to 1. If you are
# using Unix/Apache, set it to 2. Setting it 0 tries to determine
# automatically, and usually works just fine. If you use IIS yet have
# 500 error problems, try setting the variable to 2, then try 3.
$IIS = 0;
# Set this to 1 to use flock(). Highly recommended if your server supports it (most do)
$UseFlock = 1;
# If you want to use a subroutine other than DoNewsHTML for viewnews.cgi functions,
# other than search, enter the name here. e.g. 'DoHeadlineHTML'
$VNSub = 'DoNewsHTML';
# If you want to a template other than viewnews.tmpl for viewnews.cgi functions,
# enter the name here. The template file must be in your NewsPro directory
# (the same directory that viewnews.cgi is in).
$VNTmpl = 'viewnews.tmpl';
# Set this to 1 to automatically look for and load ViewNews addons.
# Generally, enable this only if you have addons installed.
# This does slow down viewnews.cgi, as it has to scan for addons
# whenever it is run.
$EnableAddons = 0;
# END OF SETTINGS (unless you encounter problems - then fill out the next section)
# SERVER PROBLEMS WORKAROUNDS
# If the script either gets its URL wrong or produces a fatal error
# about not being able to include npconfig.pl, set the following variables.
# While it won't hurt, most users don't have to.
$abspath = '';
# Set the above to the absolute path to NewsPro's directory, without
# a trailing slash. Example:
# $abspath = '/absolute/path/to/newspro';
$scripturl = '';
# Set the above to the URL to newspro.cgi. Example:
# $scripturl = 'http://www.myserver.com/newspro/newspro.cgi';
# Once again, you only need to set the above two variables if you're
# having server problems.
# END SERVER PROBLEMS WORKAROUNDS
