Jeff,

IIRC eruby doesn't automatically import the parameters (ala-PHP-- and possibly 
ASP [?]) in any fashion, and this is the way I've always handled it.  Someone 
may have a better suggestion...

Use the CGI library.

<%
	require 'cgi'
	params = CGI.new.params
%>

A common 'gotcha' with cgi.rb is the fact that CGI#params is a Hash of Arrays, 
not just a simple Hash. In most cases to access data you'll want to something 
like:
	<%= params['foo'][0] %>

Playing with cgi.rb in irb will make this apparent.

Happy erubying.

- Bruce
