0018
0019 Defines standard version numbers, with these properties:
0020
0021 * Decimal base whole numbers in the range [0,1000000000).
0022   The number range is designed to allow for a (2,2,5) triplet.
0023   Which fits within a 32 bit value.
0024 * The `major` number can be in the [0,99] range.
0025 * The `minor` number can be in the [0,99] range.
0026 * The `patch` number can be in the [0,99999] range.
0027 * Values can be specified in any base. As the defined value
0028   is an constant expression.
0029 * Value can be directly used in both preprocessor and compiler
0030   expressions for comparison to other similarly defined values.
0031 * The implementation enforces the individual ranges for the
0032   major, minor, and patch numbers. And values over the ranges
0033   are truncated (modulo).

0061 version number resulting in a preprocessor expression in the range of
0062 [0,99] or [0,99999] for the major and minor, or patch numbers
0063 respectively.
