Buby

Buby is a mashup of JRuby with the popular commercial web security testing tool Burp Suite from PortSwigger. Burp is driven from and tied to JRuby with a Java extension using the BurpExtender API. This extension aims to add Ruby scriptability to Burp Suite with an interface comparable to the Burp's pure Java extension interface.
