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