<p>APR-util's Version</p>
<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>
<p>Note that it is possible for an application to detect that it has been compiled against a different version of APU by use of the compile-time constants and the use of the run-time query function.</p>
<p>APU version numbering follows the guidelines specified in:</p>
