# 
# == What is this library? 
# 
# This library is used for communication with Nessus over XML RPC interface. 
# You can start, stop, pause and resume scan. Watch progress and status of scan, 
# download report, etc.
#
# == Requirements
# 
# Required libraries are standard Ruby libraries: uri, net/https and rexml/document. 
#
# == Usage:
# 
#  require 'nessus-xmlrpc'
#  n=NessusXMLRPC::NessusXMLRPC.new('https://localhost:8834','user','pass');
#  if n.logged_in
# 	id,name = n.policy_get_first
# 	puts "using policy ID: " + id + " with name: " + name
# 	uid=n.scan_new(id,"textxmlrpc","127.0.0.1")
#	puts "status: " + n.scan_status(uid)
# 	while not n.scan_finished(uid)
# 		sleep 10
# 	end
#	content=n.report_file_download(uid)
# 	File.open('report.xml', 'w') {|f| f.write(content) }
#  end

require 'uri'
require 'net/https'
require 'rexml/document'

# NessusXMLRPC module
# 
# Usage:
# 
#  require 'nessus-xmlrpc'
#  n=NessusXMLRPC::NessusXMLRPC.new('https://localhost:8834','user','pass');
#  if n.logged_in
# 	id,name = n.policy_get_first
# 	uid=n.scan_new(id,"textxmlrpc","127.0.0.1")
#	puts "status: " + n.scan_status(uid)
#  end
#
# Check NessusXMLRPCrexml for description of methods implemented 
# (for both NessusXMLRPCnokogiri and NessusXMLRPCrexml).
