I installed prelude with curl before realizing that the OSX version of emacs is too old for prelude. Now I can't find any documentation on how to remove it and I'm hesitant to just start deleting files in my emacs folder that have the word 'prelude' in them. Is there a command to remove this?
The simplest way is to ask prelude where it is installed. Try this (even if emacs does not fully load all prelude):
ESC-x describe-variable prelude-dir
It will tell you where prelude is being loaded from.
