Subject: Re: eRuby (making it work)

Thanks.  But what is a '.htaccess' file?

After I created it I couldn't view any of my webpages online.
The browser said:

Forbidden
You don't have permission to access /~dcarrera/ruby/0.2/first_steps.html
on this server.

Perhaps I have to add something to the .htaccess file to make the files
world readable?
