dnl Versioning:
+dnl - CURRENT (Major): Increment if the interface has changes. AGE is always
+dnl *changed* at the same time.
dnl - AGE (Micro): Increment if any interfaces have been added; set to 0
dnl if any interfaces have been removed. Removal has
dnl precedence over adding, so set to 0 if both happened.
+dnl It denotes upward compatibility.
dnl - REVISION (Minor): Increment any time the source changes; set to
dnl 0 if you incremented CURRENT.
-dnl - CURRENT (Major): Increment if the interface has changes or removals.
+dnl
+dnl To summarize. Any interface *change* increment CURRENT. If that interface
+dnl change does not break upward compatibility (ie it is an addition),
+dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed,
+dnl REVISION is set to 0, otherwise REVISION is incremented.
