   <H2> How and Where Defined </H2>
 
   The version numbers are provided as simple macros defined in the cfe_version.h header file as part of the
   API definition; these macros must expand to simple integer values, so that they can be used in simple if
   directives by the macro preprocessor.

   <H2> Identifying Development Builds </H2>
 
   In order to distinguish between development versions, we also provide a BUILD_NUMBER.
 
   The BUILD_NUMBER reflects the number of commits since the BUILD_BASELINE, a baseline git tag, for each particular
   component. The BUILD_NUMBER integer monotonically increases for a given baseline. The BUILD_BASELINE

   string also refers to the current development cycle. When a new baseline tag and codename are created, the
   BUILD_NUMBER resets to zero and begins increasing from a new baseline.
