Building the equivalent of wget in Squeak

Hello

I would like to create a simple means
of getting the contents of a web page, in the same way that wget works.
 What I hoped to do was something like:

wget url: 'http://...' show.

I found a few classes e.g. Httpurl and
also the asUrl method of the string class, but I can't quite work out how
to put it all together.  As it seems like a simple way to start learning
Squeak, I wonder if someone could point me in the right direction.

Thanks
