Vim-SyntaxHighlight: Custom Syntax Highlighting With Vim

Question

I'm trying to make my own syntax highlighting for vim. I was following the instructions in here (first answer) but I need to set a group for import and pack, and another group for func, lib, group. How can I do this?

Example of how my code should look like:

import testlib
pack builtin

func myfunc:param#type {
    testlib testcommand(param)
}

lib mylib {
    func mylibfunc:param#type {
        print(param)
    }
    func mylibfunc2:empty {
        age = ask("How old are you?\n")
        print("You are "+str(age)+" years old.")
    }
}

group mygroup {
    1: myfunc
    2: mylib
}

I'm using vim on osx Yosemite.
