  36           ar is an archival utility program used to create, modify, and
  37           extract contents from archives. An archive is a single file holding
  38           a collection of other files in a structure that makes it possible to
  39           retrieve the original individual files (called archive members).
  40           The original files' contents, mode (permissions), timestamp, owner,
  41           and group are preserved in the archive, and can be restored on
  42           extraction.
  43
  44           The stored filename is limited to 15 characters. (for more information
  45           see long filename support).
  46           ar has 60 bytes of overheads for every stored file.
  47
  48           This implementation of ar can extract archives, it cannot create or
  49           modify them.
  50           On an x86 system, the ar applet adds about 1K.
