+dnl      The implementation number of the current interface.

+dnl      The difference between the newest and oldest interfaces that

+dnl      age to current.
+dnl
+dnl Here are a set of rules to help you update your library version
+dnl information:
+dnl
+dnl  1. Start with version information of `0:0:0' for each libtool library.
+dnl  2. Update the version information only immediately before a public
+dnl     release of your software. More frequent updates are unnecessary, and
+dnl     only guarantee that the current interface number gets larger faster.
+dnl  3. If the library source code has changed at all since the last update,
+dnl     then increment revision (`c:r:a' becomes `c:r+1:a').
+dnl  4. If any interfaces have been added, removed, or changed since the last
+dnl     update, increment current, and set revision to 0.
+dnl  5. If any interfaces have been added since the last public release, then
+dnl     increment age.
+dnl  6. If any interfaces have been removed since the last public release,
+dnl     then set age to 0.
