I am using different Emacs starter kits. The problem is that each starter kit, I use different directories (for example, for prelude I use´.emacsPrelude.d´, for SciMax I use ´.emacsSciMax.d´) . But all starter kits shares a common directory inside the directories, which is called Elpa. I can't use the same directory because each has different directory structure. Is there any Emacs command to define where Elpa packages will be installed? Or can I change the Elpa directory in my ´init.el´ file?
