It's B::Xref and it's pretty cool. There is also a Devel::Xref which I eventually pursuaded CPAN to allow me to download. However, the documentation is less than clear (to me) on how to use it. I can get some output, but you have to embed it in the script, and the output is somewhat confusing. Now you've pointed out B::Xref, and demonstrated how easy it is to use, I am way impressed. It is really cool. And fast! I just tried it out on Date::Manip. Very interesting, if slightly scary reading. Thanks for posting, I can see me using that a lot. Examine what is said, not who speaks. Silence betokens consent. Love the truth but pardon error.	[reply]
