+# 1. Update the version information only immediately before a public release

+# 2. If the library source code has changed at all since the last update,
+#    then
+#    - increment AA_LIB_REVISION
+# 3. If any interfaces have been added, removed, or changed since the last
+#    update,
+#    - increment AA_LIB_CURRENT
+#    - set AA_LIB_REVISION to 0.
+# 4. If any interfaces have been added since the last public release, then
+#    - increment age.
+# 5. If any interfaces have been removed or changed since the last public
+#    release, then
+#    - set age to 0.
