I was just installing org-mode for the old vedrsion of emacs at work. Don't have root or admin, so installed it in a private directory. Had to modify my emacs load-path to be able to make things work.
Which led me to realize: emacs doesn't have FindBin. And needs it. Something that says "for everything in this file, add the directory of that fileto load-path" (but not for stuff elsewhere).
Everyone nees FindBin.
Source relative naming is a key for reducing name collisions.
Now, about the security implications...
