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