Using SA code to extract URLs ?

[Michael W. Cocke]

I was told a while back that the best way to extract urls from emails 
was to use code from SpamAssassin.  Ok - Now, I need to do just that. 
Any pointers?  I've looked thru the code in SpamCopURI, but unless there 
are some docs hidden somewhere I can't even figure out the entry point. 
 Are there some docs hidden somewhere (I hope!)?

Thanks!
