eRuby.cgi

I’m not using rails, I think if I tried I’d be way in over my head, but
I do want to use ruby in my websites, so I’m thinking eruby is the way
to go.
The problem is, I need to install it.

From what I gather, I just need to put the eruby cgi file in my cgi-bin,
and then add some code to a .htaccess file to tell it to use the
eruby.cgi to process my .rhtml files.

That seems easy enough (I sure hope it’s that easy), but I can’t find an
eruby.cgi file anywhere.
