Where is the location of /styles/main.css ?

[svn stuff]

Hello,

While looking at the source code of the HTML output of the hello.xml sample,

I noticed the css is linked thus,

<link rel="stylesheet" type="text/css" href="/styles/main.css"/>

but i couldn't find the styles folder under %cocoon%/webapps or
%cocoon%/samples.

I'm using Cocoon 2.1.10 + JDK 1.5.0_11 without a servlet container,
ie, using cocooon by itself without running it from
an app server like Tomcat.
