# SYNOPSIS
#
# AX_BOOST_PYTHON
#
# DESCRIPTION
#
# This macro checks to see if the Boost.Python library is installed. It
# also attempts to guess the correct library name using several attempts.
# It tries to build the library name using a user supplied name or suffix
# and then just the raw library.
#
# If the library is found, HAVE_BOOST_PYTHON is defined and
# BOOST_PYTHON_LIB is set to the name of the library.
#
# This macro calls AC_SUBST(BOOST_PYTHON_LIB).
#
# In order to ensure that the Python headers and the Boost libraries are
# specified on the include path, this macro requires AX_PYTHON_DEVEL and
# AX_BOOST_BASE to be called.
