-# SYNOPSIS
-#
-#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
-#
-# 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
