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