[Tobago] How to provide source code modifications?

[Helmut Swaczinna]

Hi,

I've made a small extension to the Tobago tag lib and want to provide this 
to the community.
Is there an instruction somewhere how to do this? Should I mail the output 
of "svn diff"?

The extension is an align attribute for tc:label:

<tc:label align="right" .../>

Regards
Helmut
