42    default n  # needs to be improved to be able to replace binutils ar
43    help
44      ar is an archival utility program used to create, modify, and
45      extract contents from archives. An archive is a single file holding
46      a collection of other files in a structure that makes it possible to
47      retrieve the original individual files (called archive members).
48      The original files' contents, mode (permissions), timestamp, owner,
49      and group are preserved in the archive, and can be restored on
50      extraction.
51
52      The stored filename is limited to 15 characters. (for more information
53      see long filename support).
54      ar has 60 bytes of overheads for every stored file.
55
56      This implementation of ar can extract archives, it cannot create or
57      modify them.
58      On an x86 system, the ar applet adds about 1K.
59
60      Unless you have a specific application which requires ar, you should
61      probably say N here.

68      By default the ar format can only store the first 15 characters
69      of the filename, this option removes that limitation.
70      It supports the GNU ar long filename method which moves multiple long

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

165      of the extra dpkg-deb, ar or tar options are needed, they are linked
