Hello everyone,

So I wrote this little piece of code:

[http://blog.stonean.com/2008/05/dependson.html](http://blog.stonean.com/2008/05/dependson.html)

Sorry for the blog link, but this was necessary for code formatting and  
long  
description.

Anyway, I just wanted to know if something like this already exists? If  
not, I would love feedback on how to make it better.

## thanks, andy
