    Import new 2-clause BSD licenced implementation of the bc and dc commands · 1f958cfa
    Stefan Eßer authored
    These implementations of the bc and dc programs offer a number of advantages
    compared to the current implementations in the FreeBSD base system:
    - They do not depend on external large number functions (i.e. no dependency
      on OpenSSL or any other large number library)
    - They implements all features found in GNU bc/dc (with the exception of
      the forking of sub-processes, which the author of this version considers
      as a security issue).
    - They are significantly faster than the current code in base (more than
      2 orders of magnitude in some of my tests, e.g. for 12345^100000).
    - They should be fully compatible with all features and the behavior of the
      current implementations in FreeBSD (not formally verified).
    - They support POSIX message catalogs and come with localized messages in
      Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
      and Russian.
    - They offer very detailed man-pages that provide far more information than
      the current ones.
