   7 # this script makes components of a PATH like string unique cand prints
   8 # it to stdout
   9 #
  10 # parameters
  11 # ----------
  12 #    PATH
  13 #
  14 # options
  15 # -------
  16 #     -d delimiter - default :
  17 #     -s shortens the path
  18 #
  19 # usefull enhancements: in the usage part, try to guess what was meant as
  20 # a path and echo it to stdout to not break for PATHs with blanks
