+# Rules for 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 since the last public release, then set age
+#     to 0.
