  12           ar is an archival utility program used to create, modify, and
  13           extract contents from archives.  An archive is a single file holding
  14           a collection of other files in a structure that makes it possible to
  15           retrieve the original individual files (called archive members).
  16           The original files' contents, mode (permissions), timestamp, owner,
  17           and group are preserved in the archive, and can be restored on
  18           extraction.
  19
  20           The stored filename is limited to 15 characters. (for more information
  21           see long filename support).
  22           ar has 60 bytes of overheads for every stored file.
  23
  24           This implementation of ar can extract archives, it cannot create or
  25           modify them.
  26           On an x86 system, the ar applet adds about 1K.

  36           By default the ar format can only store the first 15 characters of the
  37           filename, this option removes that limitation.
  38           It supports the GNU ar long filename method which moves multiple long
  39           filenames into a the data section of a new ar entry.
