-- Ptokax LuaScript - written by bluebear.
-- This script is a part of the pxwsa.dll packages documentation.
-- Please read the license.txt before any usage, thx.
-- ==========================================================
-- File: AsyncWhois.lua
-- Usage: +whois
-- Arg: IP/DOMAIN/HOSTNAME
-- Desc:   Provides a +whois trigger to all users.
--      It only allows one user to use it at the time
--      Please note that this is a sample script.
--      I'm not a luascripter in any way.
--      You should finish this script, if you use it for
--      other things than testing.
--      You should add code for checking if the args
--      are valid so you wont crash ptokax.
