  21 # This script is compatible with the BSD install script, but was written
  22 # from scratch.
  23 #
  24 # At Cygnus this script is duplicated as:
  25 #
  26 #     install.sh
  27 #     apache/install-sh
  28 #     dejagnu/install-sh
  29 #     expect/install-sh
  30 #     inet/install-sh
  31 #
  32 # if you change one of these, you will probably want to change them
  33 # all.  Variants of it also appear in:
  34 #
  35 #     tcl/unix/install-sh
  36 #     tk/unix/install-sh
  37 #
  38 # however these versions are the versions of this script from the
  39 # original Tcl/Tk distribution, and are somewhat different, and so
  40 # changing these will result in divergences from the Tcl/Tk
  41 # distribution.
  42 #
