  42         help
  43           ar is an archival utility program used to create, modify, and
  44           extract contents from archives. An archive is a single file holding
  45           a collection of other files in a structure that makes it possible to
  46           retrieve the original individual files (called archive members).
  47           The original files' contents, mode (permissions), timestamp, owner,
  48           and group are preserved in the archive, and can be restored on
  49           extraction.
  50
  51           The stored filename is limited to 15 characters. (for more information
  52           see long filename support).
  53           ar has 60 bytes of overheads for every stored file.
  54
  55           This implementation of ar can extract archives, it cannot create or
