CGRU is nice set of plugins and scripts maintained by Timur Hairulin (author of Afanasy).
meTools is now moved to cgru\plugins\maya\afanasy, that in my opinion is more logical then in cgru\afanasy\plugins\maya\python\meTools as before, because these scripts are supposed to use with Maya for Afanasy.
Timur, also has written meArnoldRender.py for submitting Afanasy jobs to Arnold standalone renderer.
