89 or: $0 [OPTION]... SRCFILES... DIRECTORY
90 or: $0 [OPTION]... -t DIRECTORY SRCFILES...
91 or: $0 [OPTION]... -d DIRECTORIES...
93 In the 1st form, copy SRCFILE to DSTFILE.
94 In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
95 In the 4th, create DIRECTORIES.
98 --help display this help and exit.
99 --version display version info and exit.
102 -C install only if different (preserve the last data modification time)
103 -d create directories instead of installing files.
104 -g GROUP $chgrpprog installed files to GROUP.
105 -m MODE $chmodprog installed files to MODE.
106 -o USER $chownprog installed files to USER.
107 -s $stripprog installed files.
108 -t DIRECTORY install into DIRECTORY.
109 -T report an error if DSTFILE is a directory.
