  11         help
  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.
  27
  28           Unless you have a specific application which requires ar, you should
  29           probably say N here.

  35         help
  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.

  45           bunzip2 is a compression utility using the Burrows-Wheeler block
  46           sorting text compression algorithm, and Huffman coding.  Compression
  47           is generally considerably better than that achieved by more
  48           conventional LZ77/LZ78-based compressors, and approaches the
  49           performance of the PPM family of statistical compressors.
  50
  51           The BusyBox bunzip2 applet is limited to de-compression only.
  52           On an x86 system, this applet adds about 11K.

  61           cpio is an archival utility program used to create, modify, and extract
  62           contents from archives.
  63           cpio has 110 bytes of overheads for every stored file.
  64
  65           This implementation of cpio can extract cpio archives created in the
  66           "newc" or "crc" format, it cannot create or modify them.

  96           This reduces dpkg-deb to the equivalent of "ar -p <deb> data.tar.gz | tar -zx".
  97           However it saves space as none of the extra dpkg-deb, ar or tar options are
