How to use themes with velocity?

Hi,

I'm having difficult to use the Spring themes with Velocity.
I've searched here in forum, but without success...
does anyone can show me an example?

Also, I didn't found anything like ThemeTag for Velocity, in the macros of the Spring(spring.vm)

This is an example of my velocity code:

Code:

---

<img src="$rc.contextPath/themes/$rc.theme.name/images/top_left.gif" border="0" alt="" />

---

But I would lik to get the parameters defined in <theme>.properties...

Thanks,
