Luke, have you tried to use the AssetPackager plugin? It is not totally
automatic as you have to define the scripts to be packed in one yml, but
thats okay for me. I think merging whatever JavaScript there is into a
file is not always good for files that are only included in special
views, because that would result in a file that would not be loaded from
cache because of the (minor) differences.
