config AR

    bool "ar"

    default n

    help

      ar is an archival utility program used to create, modify, and

      extract contents from archives.  An archive is a single file holding

      a collection of other files in a structure that makes it possible to

      retrieve the original individual files (called archive members).

      The original files' contents, mode (permissions), timestamp, owner,

      and group are preserved in the archive, and can be restored on

      extraction.

​

      The stored filename is limited to 15 characters. (for more information

      see long filename support).

      ar has 60 bytes of overheads for every stored file.

​

      This implementation of ar can extract archives, it cannot create or

      modify them.

      On an x86 system, the ar applet adds about 1K.

​

      Unless you have a specific application which requires ar, you should

      probably say N here.

​

config FEATURE_AR_LONG_FILENAMES

    bool "Enable support for long filenames (not need for debs)"

    default n

    depends on AR

    help

      By default the ar format can only store the first 15 characters of the

      filename, this option removes that limitation.

      It supports the GNU ar long filename method which moves multiple long

      filenames into a the data section of a new ar entry.

​

config BUNZIP2

    bool "bunzip2"

    default n

    help

      bunzip2 is a compression utility using the Burrows-Wheeler block

      sorting text compression algorithm, and Huffman coding.  Compression

      is generally considerably better than that achieved by more

      conventional LZ77/LZ78-based compressors, and approaches the

      performance of the PPM family of statistical compressors.

​

      The BusyBox bunzip2 applet is limited to de-compression only.

      On an x86 system, this applet adds about 11K.

​

      Unless you have a specific application which requires bunzip2, you

      should probably say N here.

​

config CPIO

    bool "cpio"

    default n

    help

      cpio is an archival utility program used to create, modify, and extract

      contents from archives.

      cpio has 110 bytes of overheads for every stored file.

​

      This implementation of cpio can extract cpio archives created in the

      "newc" or "crc" format, it cannot create or modify them.

​

      Unless you have a specific application which requires cpio, you should

      probably say N here.

​

config DPKG

    bool "dpkg"

    default n

    help

      dpkg is a medium-level tool to install, build, remove and manage Debian packages.

​

      This implementation of dpkg has a number of limitations, you should use the

      official dpkg if possible.

​

config DPKG_DEB

    bool "dpkg_deb"

    default n

    help

      dpkg-deb packs, unpacks and provides information about Debian archives.

​

      This implementation of dpkg-deb cannot pack archives.

​

      Unless you have a specific application which requires dpkg-deb, you should

      probably say N here.

​

config FEATURE_DPKG_DEB_EXTRACT_ONLY

    bool "extract only (-x)"
