   3 # wm-oldmenu2new: script to convert from old-style WindowMaker
   4 # menu file to the new PropertyList style of the WMRootMenu.
   5 #
   6 # Note: ex in all the Linux systems I've used is badly
   7 # broken, except for nex.  perl can be relied on however.
   8 # Re-written to use perl.

  11 #   None.
