  3# install - install a program, script, or datafile
  4# This comes from X11R5.
  5#
  6# Calling this script install-sh is preferred over install.sh, to prevent
  7# `make' implicit rules from creating a file called install from it
  8# when there is no Makefile.
  9#
 10# This script is compatible with the BSD install script, but was written
 11# from scratch.
 12#

 21# put in absolute paths if you don't have them in your path; or use env. vars.
