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