# SYNOPSIS

#

#   AX_BOOST_PYTHON

#

# DESCRIPTION

#

#   This macro checks to see if the Boost.Python library is installed. It

#   also attempts to guess the currect 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 are specified on the include

#   path, this macro requires AX_PYTHON to be called.
