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