# 
# Provides several javascript functions for determining the OS and browser versions of a client.
#
# getVersion():  returns an object with the following properties
#	os_name      -  OS name, one of the Msf::OperatingSystems constants
#	os_flavor    -  OS flavor as a string (e.g.: "XP", "2000")
#	os_sp        -  OS service pack (e.g.: "SP2", will be empty on non-Windows)
#	os_lang      -  OS language (e.g.: "en-us")
#	ua_name      -  Client name, one of the Msf::HttpClients constants
#	ua_version   -  Client version as a string (e.g.: "3.5.1", "6.0;SP2")
#	arch         -  Architecture, one of the ARCH_* constants
#
# The following functions work on the version returned in obj.ua_version
#
# ua_ver_cmp(a, b): returns -1, 0, or 1 based on whether a < b, a == b, or a > b respectively
# ua_ver_lt(a, b):  returns true if a < b
# ua_ver_gt(a, b):  returns true if a > b
# ua_ver_eq(a, b):  returns true if a == b
