vbulletin4_users

Sadly there is no documentation for this plugin

#!/usr/bin/perl
#
# Plugin to monitor the number of guests/users on a vbulletin4 forum
# Since we are using a regexp, this will work for EN forum only... adapt the regexp if your forum is not using that language.
# visual-regexp is a great help for tuning the regexp (package exists on Debian and Ubuntu repositories)
#
#
# Parameters supported:
#
#       config
#       autoconf
#
# Configurable variables
#
#       url  to online.php, this page is part of vbulletin distribution, pp=1 so the page is fast to load and doesn't give us too many unwanted info
#
# $Log$
#
#
# Not sure about those lines...
#
# Magic markers:
#%# family=auto
#%# capabilities=autoconf
