23 dnl ---------------------------------------------------------------------------
24 dnl Versioning:
25 dnl  - CURRENT (Major):  Increment if the interface has changes. AGE is always
26 dnl                      *changed* at the same time.
27 dnl  - AGE (Micro):      Increment if any interfaces have been added; set to 0
28 dnl                      if any interfaces have been removed. Removal has 
29 dnl                      precedence over adding, so set to 0 if both happened.
30 dnl                      It denotes upward compatibility.
31 dnl  - REVISION (Minor): Increment any time the source changes; set to 
32 dnl                      0 if you incremented CURRENT.
33 dnl
34 dnl  To summarize. Any interface *change* increment CURRENT. If that interface
35 dnl  change does not break upward compatibility (ie it is an addition), 
36 dnl  increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed, 
37 dnl  REVISION is set to 0, otherwise REVISION is incremented.
