How would I go to convert a GMod 12 spawnlist to work with GMod 13?

Because I have some decent ones I want to use still :frowning:

And uh, if anyone is feeling nice and/or wants to see what spawnlists I have/want: http://www.mediafire.com/download/z6auap9zx0yu9sb/spawnlists.rar

(Probably a repeat, sorry in advance. Just really bugging me)
