    8     config AR
    9     bool "ar"
    10     default n
    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.
    30    
    31     config FEATURE_AR_LONG_FILENAMES
    32     bool "Enable support for long filenames (not need for debs)"
    33     default n
    34     depends on AR
    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.
    40    
    41     config BUNZIP2
    42     bool "bunzip2"
    43     default n
    44     help
    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.
    53    
    54     Unless you have a specific application which requires bunzip2, you
    55     should probably say N here.
    56    
    57     config CPIO
    58     bool "cpio"
    59     default n
    60     help
    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.
    67    
    68     Unless you have a specific application which requires cpio, you should
    69     probably say N here.
    70    
    71     config DPKG
    72     bool "dpkg"
    73     default n
    74     help
    75     dpkg is a medium-level tool to install, build, remove and manage Debian packages.
    76    
    77     This implementation of dpkg has a number of limitations, you should use the
    78     official dpkg if possible.
    79    
    80     config DPKG_DEB
    81     bool "dpkg_deb"
    82     default n
    83     help
    84     dpkg-deb packs, unpacks and provides information about Debian archives.
    85    
    86     This implementation of dpkg-deb cannot pack archives.
    87    
    88     Unless you have a specific application which requires dpkg-deb, you should
    89     probably say N here.
    90    
    91     config FEATURE_DPKG_DEB_EXTRACT_ONLY
    92     bool "extract only (-x)"
    93     default n
    94     depends on DPKG_DEB
    95     help
    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
    98     needed, they are linked to internally.
    99    
    100     config GUNZIP
    101     bool "gunzip"
    102     default n
    103     help
    104     gunzip is used to decompress archives created by gzip.
    105     You can use the `-t' option to test the integrity of
    106     an archive, without decompressing it.
    107
