Re: Porting librsvg to an Embedded Platform

Thanks a lot Dominic. Your comments have been definitely helpful. We 
basically wish to display simple SVG animations on our system. Our 
system is not intended to be as powerful as the Nokia 770 platform.

One more question: Would it be possible to port librsvg on a system 
without an OS?

thanks and regards
