+# Do the releases and library versioning according to following rules:

+#  - If any code has changed in library, increment [LIB]_REVISION
+#  - If functions were added, set [LIB]_REVISION to 0
+#  - If functions were added, removed or changed, increment [LIB]_CURRENT
+#  - If functions were added, increment [LIB]_AGE
+#  - If functions were removed, set [LIB]_AGE to 0
+#
+# where [LIB] is LIBSILC and LIBSILCCLIENT, and where "functions" means
+# functions public interfaces.
+#
+# The LIB_BASE_VERSION defines the SILC software major.minor version and 
+# it is increment only when these version numbers actually change.
