5# SYNOPSIS
6#
7#   AX_BOOST_BASE([MINIMUM-VERSION])
8#
9# DESCRIPTION
10#
11#   Test for the Boost C++ libraries of a particular version (or newer)
12#
13#   If no path to the installed boost library is given the macro searchs
14#   under /usr, /usr/local, /opt and /opt/local and evaluates the
15#   $BOOST_ROOT environment variable. Further documentation is available at
16#   <http://randspringer.de/boost/index.html>.
17#
18#   This macro calls:
19#
20#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
21#
22#   And sets:
23#
24#     HAVE_BOOST
