+ * 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:
+ *
+ *     http://apr.apache.org/versioning.html
