   or: $0 [OPTION]... SRCFILES... DIRECTORY

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.
