# This file contains some variable definitions that are supposed to
# make your life easier when dealing with ports related to the Python
# language. It's automatically included when USE_PYTHON or PYTHON_VERSION
# is defined in the ports' makefile. Define PYTHON_VERSION to override the
# defaults that USE_PYTHON would give you. If your port requires only some
# set of Python versions, you can define USE_PYTHON as [min]-[max] or
# min+. (eg. 2.1-2.3, 2.0+ or -2.2)
#
# The variables:
#
# PYTHONBASE:	Python port's installation prefix.
#				default: ${LOCALBASE}
#
# PYTHON_CMD:	Python's command line file name, including the version
#				number (used for dependencies).
#				default: ${PYTHONBASE}/bin/${PYTHON_VERSION}
#
# PYTHON_DISTFILE:	The ${DISTFILE} for your python version. Needed for
#					extensions like Tkinter, py-gdbm and py-expat, which
#					are built from sources contained in the Python
#					distribution.
#
# PYTHON_SITE_SUBDIR:	The ${MASTER_SITE_SUBDIR} for your python version.
#
# PYTHON_INCLUDEDIR:	Location of the Python include files.
#						default: ${PYTHONBASE}/include/${PYTHON_VERSION}
#
# PYTHON_LIBDIR:	Base of the python library tree
#					default: ${PYTHONBASE}/lib/${PYTHON_VERSION}
#
# PYTHON_PKGNAMEPREFIX:	Use this as a ${PKGNAMEPREFIX} to distinguish
#						packages for different Python versions.
#						default: py${PYTHON_SUFFIX}-
#
# PYTHON_PKGNAMESUFFIX:	If your port's name is more popular without `py-'
#						prefix, use this as a ${PKGNAMESUFFIX} alternatively.
#						default: -py${PYTHON_SUFFIX}
#
# PYTHON_PLATFORM:	Python's idea of the OS release.
#					XXX This is faked with ${OPSYS} and ${OSREL} until I  
#					find out how to delay defining a variable until after 
#					a certain target has been built. 
#
# PYTHON_PORTSDIR:	The source of your binary's port. Needed for the
#					RUN_DEPENDS.
#
# PYTHON_PORTVERSION:	Version number suitable for ${PORTVERSION}.
#
# PYTHON_REL:		Version number in numerical format, to ease
#					comparison in makefiles
#
# PYTHON_SITELIBDIR:	Location of the site-packages tree. Don't change,
#					unless you know what you do.
#						default: ${PYTHON_LIBDIR}/site-packages
#
# PYTHON_SUFFIX:	Yet another short version number, primarily intended
#					for ${PYTHON_PKGNAMEPREFIX}.
#
# PYTHON_VERSION:	Version of the python binary in your ${PATH}, in the 
#					format "python2.0".	Set this in your makefile in case you
#					want to build extensions with an older binary.
#					default: depends on the version of your python binary
#
# PYTHON_WRKSRC:	The ${WRKSRC} for your python version. Needed for
#					extensions like Tkinter, py-gdbm and py-expat, which
#					are built from sources contained in the Python
#					distribution.
#
# There are PREFIX-clean variants of the PYTHON_*DIR variables above.
# They are meant to be used in the installation targets.
#
# PYTHONPREFIX_INCLUDEDIR:	default: ${PREFIX}/include/${PYTHON_VERSION}
# PYTHONPREFIX_LIBDIR:		default: ${PREFIX}/lib/${PYTHON_VERSION}
# PYTHONPREFIX_SITELIBDIR:	default: ${PYTHONPREFIX_LIBDIR}/site-packages
#
# PYDISTUTILS:	Dependency line for the distutils extension. As of Python-2.0,
#				the distutils are in the base distribution.
#
# PYNUMERIC:	Dependency line for the numeric extension. Py-Numeric-17
# 				is the last release that works with Python versions older
#				than 1.6.
#
# PYXML:		Dependency line for the XML extension. As of Python-2.0,
#				this extension is in the base distribution.
#
# USE_PYTHON_PREFIX:	Says that the port installs in ${PYTHONBASE}.
#
# USE_PYDISTUTILS:	Use distutils as do-build and do-install target.
#
# PYDISTUTILS_BUILDARGS:	Arguments to build with distutils.
#							default: <empty>
#
# PYDISTUTILS_INSTALLARGS:	Arguments to install with distutils.
#							default: -c -O1 --prefix=${PREFIX}
#
# PYSETUP:		Name of the setup script used by the distutils package.
#				default: setup.py
