Should really have been done as part of bumping the library version
(0.0.2.dev in configure.ac).

+# Shared library interface version, i.e. -version-info to Libtool,
+# expressed as three integers CURRENT:REVISION:AGE.
+
+# CURRENT is the version number of the current interface.  Increment
+#        CURRENT when the library interface changes.
+
+# REVISION is the version number of the _implementation_ of the
+#          CURRENT interface.  Set REVISION to 0 when CURRENT changes,
+#          else increment.
+
+# AGE is the number of interfaces this library implements, i.e. how
+#     many versions before CURRENT that are supported.  Increment AGE
+#     when the library interface is _extended_.  Set AGE to 0 when the
+#     library interface is _changed_.
