  19 Defines standard version numbers, with these properties:
  20
  21 * Decimal base whole numbers in the range [0,1000000000).
  22   The number range is designed to allow for a (2,2,5) triplet.
  23   Which fits within a 32 bit value.
  24 * The `major` number can be in the [0,99] range.
  25 * The `minor` number can be in the [0,99] range.
  26 * The `patch` number can be in the [0,99999] range.
  27 * Values can be specified in any base. As the defined value
  28   is an constant expression.
  29 * Value can be directly used in both preprocessor and compiler
  30   expressions for comparison to other similarly defined values.
  31 * The implementation enforces the individual ranges for the
  32   major, minor, and patch numbers. And values over the ranges
  33   are truncated (modulo).

  61 version number resulting in a preprocessor expression in the range of
  62 [0,99] or [0,99999] for the major and minor, or patch numbers
  63 respectively.
