# Copied and modified from ax_boost_chrono with ROSE-specific changes.
#
# SYNOPSIS
#
# AX_BOOST_PYTHON
#
# DESCRIPTION
#
# Test for Python library from the Boost C++ libraries. The macro requires
# a preceding call to AX_BOOST_BASE. Further documentation is available at
# <http:https://randspringer.de/boost/index.html>.
#
# This macro calls:
#
# AC_SUBST(BOOST_PYTHON_LIB)
#
# And sets:
#
# HAVE_BOOST_PYTHON
