Versioning API for libapreq.
<p>
There are several different mechanisms for accessing the version. There is a string form, and a set of numbers; in addition, there are constants which can be compiled into your application, and you can query the library being used for its actual version.<p>
Note that it is possible for an application to detect that it has been compiled against a different version of libapreq by use of the compile-time constants and the use of the run-time query function.<p>
libapreq version numbering follows the guidelines specified in:<p>
