;;;     Copyright (C) 1994 Heiko Muenkel
;;;     email: muenkel@tnt.uni-hannover.de
;;;
;;;  Changed 18-May-1995, Kyle Jones
;;;    Removed the need for the utils.el package and references thereto.
;;;    Changed file-truename calls to tree-menu-file-truename so
;;;    the calls could be made compatible with FSF Emacs 19's
;;;    file-truename function.
;;;  Changed 30-May-1995, Kyle Jones
;;;    Renamed functions: tree- -> vm-menu-hm-tree.
;;;  Changed 5-July-1995, Kyle Jones
;;;    Removed the need for -A in ls flags.
;;;    Some systems' ls don't support -A.
