# NPLIB.pl

# See newspro.cgi for license information.
# Location of nsettings.cgi.
# It is important that your nsettings.cgi is not visible over the Web.
# One way of accomplishing it is to move it to a different directory,
# and give it another name. You can set the following option to the new
# path of nsettings.cgi. Use an absolute path (no trailing slash).
# Example:
# $nsettingspath = '/usr/home/me/securefiles/newspro-settings-5432.cgi';
$nsettingspath = '';
# Lifespan of cookies, in seconds.
# 7776000 seconds is equal to 90 days.
$cookieExpLength = 7776000;
