+dnl Below are the numbers to handle libabigail.so's versionning

+dnl libraries' compatibility.
+dnl
+dnl Below are the rules to follow to update the three numbers
+dnl (LIBABIGAIL_SO_CURRENT, LIBABIGAIL_SO_REVISION and LIBABIGAIL_SO_AGE):
+dnl
+dnl 1. If the library source code has changed at all since the last
+dnl    update, then increment LIBABIGAIL_SO_REVISION ('C:R:A' becomes
+dnl    'C:R+1:A').
+dnl 
+dnl 2. If any interfaces have been added, removed, or changed since
+dnl    the last update, increment LIBABIGAIL_SO_CURRENT, and set
+dnl    LIBABIGAIL_REVISION to 0.
+dnl 
+dnl 3. If any interfaces have been added since the last public release,
+dnl    then increment LIBABIGAIL_SO_AGE.
+dnl 
+dnl 4. If any interfaces have been removed or changed since the last
+dnl     public release, then set LIBABIGAIL_SO_AGE to 0.
