# SYNOPSIS
#
# AX_BOOST_CONTEXT
#
# DESCRIPTION
#
# Test for Context 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_CONTEXT_LIB)
#
# And sets:
#
# HAVE_BOOST_CONTEXT
