Displaying ruby content in rhtml

Hi everyone,

I am a newbie to RoR. I installed the Instant Rails package 1.7, and
with scaffold, I was able to create and connect to a database.
However, when I embed some code in rhtml(list.rhtml in the tutorial
there), it does not display in browser. I can see the html part on the
screen without problem, but the ruby part does not get processed at
all.
When I try a simple rhtml file such as below,

<% puts ... %> or <% print ...%> achieves very little (at best it will
output to your server's log file).
You need to be using <%= which inserts the result of evaluating it's
contents, ie <%= Time.now %>
