How to update out of date wow addons

This tutorial is on how to update your World of Warcraft add-ons manually. Within each add-on folder there is a file called (nameofthemod.toc) within this file there is line called Interface and a line with version number of the mod. All you do is change the two and save changes and reboot World of Warcraft. This doesn't fix broken mods. This just gets rid of the annoying, "mod out of date" message.
