+libunwind_la_LDFLAGS = -version-info 0:0:0
+
+# The -version-info flag accepts an argument of the form
+# `current[:revision[:age]]'. So, passing `-version-info 3:12:1' sets
+# current to 3, revision to 12, and age to 1.
+
+# If either revision or age are omitted, they default to 0. Also note
+# that age must be less than or equal to the current interface number.
+
+# Here are a set of rules to help you update your 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.
