-# SYNOPSIS
-#
-# AX_BOOST_CHRONO
-#
-# DESCRIPTION
-#
-# Test for System library from the Boost C++ libraries. The macro requires
-# a preceding call to AX_BOOST_BASE. Further documentation is available at
-# <http://randspringer.de/boost/index.html>.
-#
-# This macro calls:
-#
-# AC_SUBST(BOOST_CHRONO_LIB)
-#
-# And sets:
-#
-# HAVE_BOOST_CHRONO
