+# SYNOPSIS
+#
+#   AX_BOOST_SERIALIZATION
+#
+# DESCRIPTION
+#
+#   Test for Serialization library from the Boost C++ libraries. The macro
+#   requires a preceding call to AX_BOOST_BASE.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_SERIALIZATION_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_SERIALIZATION
