Hi all,  
I need to embed the FireFox engine in a pet project of mine I’m  
working  
on. I have a couple of questions.

1. Does such a Gem already exist? There’s no point in re-inventing  
the wheel if it does.
2. If not, where can I find a good example of writing a gem with  
embedded code? I’ve looked online, and all the tutorials I’ve found  
use  
only ruby code. I was thinking that the MySQL gem with native  
drivers might  
be a good example, but I’d like to look at a couple more before I  
proceed.

Thanks,  
Todd
