  83. In the 1st form, copy SRCFILE to DSTFILE.
  84. In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
  85. In the 4th, create DIRECTORIES.
  86. Options:
  87. --help display this help and exit.
  88. --version display version info and exit.
  89. -c (ignored)
  90. -C install only if different (preserve data modification time)
  91. -d create directories instead of installing files.
  92. -g GROUP $chgrpprog installed files to GROUP.
  93. -m MODE $chmodprog installed files to MODE.
  94. -o USER $chownprog installed files to USER.
  95. -p pass -p to $cpprog.
  96. -s $stripprog installed files.
  97. -S SUFFIX attempt to back up existing files, with suffix SUFFIX.
  98. -t DIRECTORY install into DIRECTORY.
  99. -T report an error if DSTFILE is a directory.
  100. Environment variables override the default commands:
  101. CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
  102. RMPROG STRIPPROG
  103. By default, rm is invoked with -f; when overridden with RMPROG,
  104. it's up to you to specify -f if you want it.
  105. If -S is not specified, no backups are attempted.
