# SYNOPSIS
#
#   AX_BOOST_UNIT_TEST_FRAMEWORK
#
# DESCRIPTION
#
#   Test for Unit_Test_Framework 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_UNIT_TEST_FRAMEWORK_LIB)
#
#   And sets:
#
#     HAVE_BOOST_UNIT_TEST_FRAMEWORK
