  44 # Rules for library version information:
  45 #
  46 #  1. Start with version information of `0:0:0' for each libtool library.
  47 #  2. Update the version information only immediately before a public release of
  48 #     your software. More frequent updates are unnecessary, and only guarantee
  49 #     that the current interface number gets larger faster.
  50 #  3. If the library source code has changed at all since the last update, then
  51 #     increment revision (`c:r:a' becomes `c:r+1:a').
  52 #  4. If any interfaces have been added, removed, or changed since the last update,
  53 #     increment current, and set revision to 0.
  54 #  5. If any interfaces have been added since the last public release, then increment
  55 #     age.
  56 #  6. If any interfaces have been removed since the last public release, then set age
  57 #     to 0.
