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