Oh, I didn't know about that. I actually was thinking of doing that in Perl, 
but then I was not sure I could depend on the XML modules. Since Qt is 
already a dependency, this should not have issues... 

And then, i wanted to try out the Qt QDOM stuff. 

Anyway, I'll check the marble sources too. Thank you for the info. 

Do you think it could be useful to strip the icons too? As I said, for 
compressed icons my program shaves off a 5% of the size.

Well, there are only 6 decimals or so, but you are right. Actually I was 
thinking about that too. And maybe colors can be simplified too. At least, 
"#000000;" could be converted to "#000;"
