 * @brief This source file contains the implementation of rtems_version(),
 *   rtems_version_control_key(), rtems_version_major(), rtems_version_minor(),
 *   and rtems_version_revision().
 *
 * The version strings are created from the various pieces of version
 * information.  The main version number is part of the build system and is
 * stamped into <rtems/score/cpuopts.h>.  The version control key string is
 * extracted from the version control tool when the code is being built and is
 * updated if it has changed.  It is defined in "version-vc-key.h".  The key
 * may indicate there are local modification.
