More examples using libcss

Hi,

I wanted to write a css spriter using libcss to parse css files. I was looking at the example provided in the code, I find that the example is very limited and not very clear. Is there some place where I can find more examples which use libcss. What I am looking at is some kind of event based API where my functions get called when parsing a ruleset,rule, etc. Similar to libcroco.

Thanks
