This is a zip file that contains the addons that Belgor uses. If you are lazy and just want to get addons fast so you can raid, download this zip file and extract the files into the interface folder in your wow.
NB! this contains a LOT more addons than you need, only pick those you want.
You need to click "load out of date addons" to get them all to work since blizzard keeps bumping the version.
This will often be the most updated files as they are the ones Belgor currently uses. Not not all theese addons are required.
