nnheader-find-etc-directory

nnheader-find-etc-directory is a compiled Lisp function in `nnheader.el'.

(nnheader-find-etc-directory PACKAGE &optional FILE FIRST)

Go through `load-path' and find the "../etc/PACKAGE" directory.
This function will look in the parent directory of each `load-path'
entry, and look for the "etc" directory there.
If FILE, find the ".../etc/PACKAGE" file instead.
If FIRST is non-nil, return the directory or the file found at the
first. Otherwise, find the newest one, though it may take a time.
