Motivation:
We currently have a discussion in Germany whether it is illegal or not to link to another website which links one way or another and in as many hobs as you can imagine to a website containing some criminal data. As you may notice the amount of links in a network will approximately grow in exponential correlation to the count of found nodes. Well, a County Court think it is illegal but there are other opinions.
For some finger training i wrote a little Perl module which will fetch a website, extracts the links and checks them again for links. And so on.
Status:
At the moment you can just output found links and their amount. It starts with a single URL end stops at doomsday. So you better defined a maximum link depth. 
Maybe I will write more code later. Maybe some fancy graph or some nice looking statistics. Or maybe it is better to improve the code. I don’t know…
The Code:
If you like you can fetch a tarball of Link::Tester for your interest and research.
