	Now build and install (to the $prefix tree) with e.g.

	To use Rivet, we recommend reading HepMC files from a file
	or pipe (the latter may be made with mkfifo) using the
	'rivet' executable.

	For a more pleasant command line experience, you can include
	the data/rivet-completion file into your .bashrc file,
	or your bash_completion.d directory if you have one.

	The rivetenv.*sh files will not be installed, but can help you
	to set up a Rivet runtime environment in future.

	# SYNOPSIS
	#
	# AX_PYTHON_DEVEL([version])
	#
	# DESCRIPTION
	#
	# Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
	# in your configure.ac.
	#
	# This macro checks for Python and tries to get the include path to
	# 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output
	# variables. It also exports $(PYTHON_EXTRA_LIBS) and
	# $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
	#
	# You can search for some particular version of Python by passing a
	# parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
	# note that you have to pass also an operator along with the version to
	# match, and pay special attention to the single quotes surrounding the
	# version number. Don't use "PYTHON_VERSION" for this: that environment
	# variable is declared as precious and thus reserved for the end-user.
	#
	# This macro should work for all versions of Python >= 2.1.0. As an end
	# user, you can disable the check for the python version by setting the
	# PYTHON_NOVERSIONCHECK environment variable to something else than the
	# empty string.
	#
	# If you need to use this macro for an older Python version, please
	# contact the authors. We're always open for feedback.
