+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt and /opt/local and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST
