   9 # 1. If the library source code has changed at all since the last update,
  10 #    then increment revision (‘c:r:a’ becomes ‘c:r+1:a’).
  11 # 2. If any interfaces have been added, removed, or changed since the last update,
  12 #    increment current, and set revision to 0.
  13 # 3. If any interfaces have been added since the last public release, then increment age.
  14 # 4. If any interfaces have been removed or changed since the last public release,
  15 #    then set age to 0.
