# Calling this script install-sh is preferred over install.sh, to prevent
# `make' implicit rules from creating a file called install from it
# when there is no Makefile.
#
# This script is compatible with the BSD install script, but was written
# from scratch.  It can only install one file at a time, a restriction
# shared with many OS's install programs.

# set DOITPROG to echo to test this script

# Don't use :- since 4.3BSD and earlier shells don't like it.
doit="${DOITPROG-}"

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

In the 1st form, copy SRCFILE to DSTFILE.
In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
In the 4th, create DIRECTORIES.

Options:
-c         (ignored)
-d         create directories instead of installing files.
-g GROUP   $chgrpprog installed files to GROUP.
-m MODE    $chmodprog installed files to MODE.
-o USER    $chownprog installed files to USER.
-s         $stripprog installed files.
-t DIRECTORY  install into DIRECTORY.
-T         report an error if DSTFILE is a directory.
--help     display this help and exit.
--version  display version info and exit.
