    33 bool "ar"
    34 default n
    35 help
    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.
    51
    52 Unless you have a specific application which requires ar, you should
    53 probably say N here.

    59 help
    60 By default the ar format can only store the first 15 characters
    61 of the filename, this option removes that limitation.
    62 It supports the GNU ar long filename method which moves multiple long
    63 filenames into a the data section of a new ar entry.

    69 bunzip2 is a compression utility using the Burrows-Wheeler block

    71 is generally considerably better than that achieved by more
    72 conventional LZ77/LZ78-based compressors, and approaches the
    73 performance of the PPM family of statistical compressors.
