  # Look for program[s] somewhere in $PATH.

  # Options:
  #  -s
  #    Do not print out full pathname. (silent)
  #  -pPATHNAME
  #    Look in PATHNAME instead of $PATH
  #
  # Usage:
  #  PrintPath [-s] [-pPATHNAME] program [program ...]

  # Now we make the adjustments required for OS/2 and everyone
  # else :)
  #
  # First of all, all OS/2 programs have the '.exe' extension.
  # Next, we adjust PATH (or what was given to us as PATH) to
  # be whitespace seperated directories.
  # Finally, we try to determine the best flag to use for
  # test/[] to look for an executable file. OS/2 just has '-r'
  # but with other OSs, we do some funny stuff to check to see
  # if test/[] knows about -x, which is the prefered flag.
