23 *
24 * APR-util's Version
25 *
26 * There are several different mechanisms for accessing the version. There
27 * is a string form, and a set of numbers; in addition, there are constants
28 * which can be compiled into your application, and you can query the library
29 * being used for its actual version.
30 *
31 * Note that it is possible for an application to detect that it has been
32 * compiled against a different version of APU by use of the compile-time
33 * constants and the use of the run-time query function.
34 *
35 * APU version numbering follows the guidelines specified in:
