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