    Well, I think if you are an experienced programmer in other general
    purpose languages then C will be fairly easy to pickup, but I can tell
    you that doing a route table is not an easy project (even for me!)
    so you are going to have your work cut out for you!  C is a very
    unforgiving language when it comes to mistakes :-)
