[otrs] Bug Tracking - or other bug tracking integration

Sorry for bringing this up as I can see from google searches that this question is asked quite often. With that said for some reason i am unable to find an answer. Is there any bug tracking capabilities in OTRS? or is there any integration with a bug tracking software? (Bugzilla preferred) I am looking for a solution to handle our helpdesk and also something to handle out websites bugs and feature requests. I don't mind if they are two separate systems, but it would be nice to generate bugs from tickets. I am very open to any suggestions. Thank you. Clay
