+# 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
+#
+# LAST MODIFICATION
