 # This is _NOT_ the library release version, it's an API version.
 # Please read Chapter 6 "Library interface versions" of the libtool
 # documentation before making any modification
+#
 # http://sources.redhat.com/autobook/autobook/autobook_91.html
+#
+# The version scheme used by Libtool tracks interfaces, where an interface
+# is the set of exported entry points into the library. All Libtool libraries
+# start with `-version-info' set to `0:0:0' -- this will be the default
+# version number if you don't explicitly set it on the Libtool link command
+# line. The meaning of these numbers (from left to right) is as follows:
+#
+# current
+#    The number of the current interface exported by the library. A current
+#    value of `0', means that you are calling the interface exported by this
+#    library interface 0.
+#
+# revision
+#    The implementation number of the most recent interface exported by this
+#    library. In this case, a revision value of `0' means that this is the 
+#    first implementation of the interface.
+#
+#    If the next release of this library exports the same interface, but has
+#    a different implementation (perhaps some bugs have been fixed), the
+#    revision number will be higher, but current number will be the same.
+#    In that case, when given a choice, the library with the highest revision
+#    will always be used by the runtime loader.
+#
+# age
+#    The number of previous additional interfaces supported by this library.
+#    If age were `2', then this library can be linked into executables which
+#    were built with a release of this library that exported the current
+#    interface number, current, or any of the previous two interfaces.
+#
+#    By definition age must be less than or equal to current. At the outset,
+#    only the first ever interface is implemented, so age can only be `0'. 
+#
+# 1. If you have changed any of the sources for this library, the revision
+#    number must be incremented.
+#    This is a new revision of the current interface.
+#
+# 2. If the interface has changed, then current must be incremented, and
+#    revision reset to `0'.
+#    This is the first revision of a new interface.
+#
+# 3. If the new interface is a superset of the previous interface (that is, 
+#    if the previous interface has not been broken by the changes in this 
+#    new release), then age must be incremented.
+#    This release is backwards compatible with the previous release.
+#
+# 4. If the new interface has removed elements with respect to the previous
+#    interface, then you have broken backward compatibility and age must be
+#    reset to `0'.
+#    This release has a new, but backwards incompatible interface.
+#
+# For example, if the next release of the library included some new commands
+# for an existing socket protocol, you would use -version-info 1:0:1.
+# This is the first revision of a new interface. This release is backwards
+# compatible with the previous release.
+#
+# Later, you implement a faster way of handling part of the algorithm at the
+# core of the library, and release it with -version-info 1:1:1. This is a new
+# revision of the current interface.
+#
+# Unfortunately the speed of your new implementation can only be fully
+# exploited by changing the API to access the structures at a lower level,
+# which breaks compatibility with the previous interface, so you release it
+# as -version-info 2:0:0. This release has a new, but backwards incompatible
+# interface.
