# 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
