  This variable may be risky if used as a file-local variable.

Documentation:
List of directories to search for files to load.
Each element is a string (directory file name) or nil (meaning
‘default-directory’).
This list is consulted by the ‘require’ function.
Initialized during startup as described in Info node ‘(elisp)Library Search’.
Use ‘directory-file-name’ when adding items to this path.  However, Lisp
programs that process this list should tolerate directories both with
and without trailing slashes.
