-# This file provides several macros to use the various Boost libraries.
-# The first macro is BOOST_REQUIRE. It will simply check if it's possible to
-# find the Boost headers of a given (optional) minimum version and it will
-# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to
-# your configure so that users can specify non standard locations.
-# If the user's environment contains BOOST_ROOT and --with-boost was not
-# specified, --with-boost=$BOOST_ROOT is implicitly used.
-# For more README and documentation, go to http://github.com/tsuna/boost.m4
-# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,
-# simply read the README, it will show you what to do step by step.
