##
# This module requires Metasploit: http://metasploit.com/download
# Current source: https://github.com/rapid7/metasploit-framework
##

##
# This module is based on, inspired by, or is a port of a plugin available in
# the Onapsis Bizploit Opensource ERP Penetration Testing framework -
# http://www.onapsis.com/research-free-solutions.php.
# Mariano Nunez (the author of the Bizploit framework) helped me in my efforts
# in producing the Metasploit modules and was happy to share his knowledge and
# experience - a very cool guy. I'd also like to thank Chris John Riley,
# Ian de Villiers and Joris van de Vis who have Beta tested the modules and
# provided excellent feedback. Some people just seem to enjoy hacking SAP :)
