+| DEFINING A CUSTOM SHARED OBJECT NUMBER |
++----------------------------------------+
+
+The shared object's version number is extracted from `mfapi.h'.
+
+Alternatively, a custom version number can be defined for `libmilter.so'.
+The custom number can consist of oen, two, or three numbers
+(libmilter.so.1.2.3).
+
+To use a custom SO version number, add the following, according to your
+needs, to your `site.config.m4':
+
+  define(`conf_libmilter_CUSTOM_SOMAJOR', `3')dnl
+  define(`conf_libmilter_CUSTOM_SOMINOR', `1')dnl
+  define(`conf_libmilter_CUSTOM_SOPATCH', `5')dnl
+
+This will result in `libmilter.so.3.1.5' to be built.
