105 or: $0 [OPTION]... -t DIRECTORY SRCFILES...
106 or: $0 [OPTION]... -d DIRECTORIES...
108 In the 1st form, copy SRCFILE to DSTFILE.
109 In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
110 In the 4th, create DIRECTORIES.
113 --help display this help and exit.
114 --version display version info and exit.
117 -C install only if different (preserve the last data modification time)
118 -d create directories instead of installing files.
119 -g GROUP $chgrpprog installed files to GROUP.
120 -m MODE $chmodprog installed files to MODE.
121 -o USER $chownprog installed files to USER.

123 -t DIRECTORY install into DIRECTORY.
