dnl Here are a set of rules to help you update your library version
dnl information:

dnl 1. Start with version information of ‘0:0:0’ for each libtool
dnl 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
dnl update, then increment revision (‘c:r:a’ becomes ‘c:r+1:a’).
dnl 4. If any interfaces have been added, removed, or changed since
dnl the last update, increment current, and set revision to 0.
dnl 5. If any interfaces have been added since the last public
dnl release, then increment age.
dnl 6. If any interfaces have been removed or changed since the last
dnl public release, then set age to 0.
