42 dnl - AGE (Micro): Increment if any interfaces have been added; set to 0
43 dnl if any interfaces have been removed. Removal has

46 dnl - REVISION (Minor): Increment any time the source changes; set to

50 dnl change does not break upward compatibility (ie it is an addition),
51 dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed,
