Hello all

I'm doing the hello word example out of this book called Agile Web
Development with Rails but I can't get a result from the browser.

I've only had this working on windows upto now and I really would
like to get rails working on linux.

I'm just getting started in Ruby on Rails and if anybody can help
that'll be grand.

mark.

Browser output:

Not Found
`/say/hello' not found.
