# 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_MASTER_SITES
#					- The ${MASTER_SITES} for your python version. (You must
#					  use this instead of ${MASTER_SITE_PYTHON} to support
#					  python-devel port.)
#
# PYTHON_MASTER_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.
# PYNUMPY			- Dependency line for the new numeric extension.
#                     py-numpy, Py-Numeric is deprecated.
#
# PYXML				- Dependency line for the XML extension. As of Python-2.0,
#					  this extension is in the base distribution.
#
# PYEXPAT			- Dependency line for the Expat XML Parser. As of Python-2.3.2,
#					  this module is in the base distribution.
#
# PYCTYPES			- Dependency line for the ctypes package. As of Python-2.5,
#					  this module is in the base distribution.
#
# PYHASHLIB			- Dependency line for the hashlib package. As of Python-2.5,
#					  this module is in the base distribution.
#
# PYWSGIREF			- Dependency line for the wsgiref package. As of Python-2.5,
#					  this module is in the base distribution.
#
# USE_PYTHON_PREFIX	- Says that the port installs in ${PYTHONBASE}.
#
# USE_PYDISTUTILS	- Use distutils as do-configure, do-build and do-install
#					  targets.
#
# PYDISTUTILS_CONFIGURE_TARGET
#					- Pass this command to distutils on configure stage.
#					  default: config
#
# PYDISTUTILS_BUILD_TARGET
#					- Pass this command to distutils on build stage.
#					  default: build
#
# PYDISTUTILS_INSTALL_TARGET
#					- Pass this command to distutils on install stage.
#					  default: install
#
# PYDISTUTILS_CONFIGUREARGS
#					- Arguments to config with distutils.
#					  default: <empty>
#
# PYDISTUTILS_BUILDARGS
#					- Arguments to build with distutils.
#					  default: <empty>
#
# PYDISTUTILS_INSTALLARGS
#					- Arguments to install with distutils.
#					  default: -c -O1 --prefix=${PREFIX}
#
# PYSETUP			- Name of the setup script used by the distutils package.
#					  default: setup.py
#
# USE_TWISTED		- If this option is just yes then build and run
#					  the dependence to twistedCore is added. Alternatively
#					  here can be listed specific components of twisted
#					  framework, available components are: web, web2, lore,
#					  news, words, pair,mail, names, xish, runner, flow and
#					  conch. Note that core component is required for any of
#					  this optional components.
#
# USE_TWISTED_BUILD	- Same as previous but add only build dependency.
#
# USE_TWISTED_RUN	- Same as USE_TWISTED but add only run dependency.
#
# USE_ZOPE			- Use Zope - an object-based web application platform, this
#					  also sets up:
# ZOPEBASEDIR		- relative base directory of zope server
# SZOPEBASEDIR		- absolute base directory of zope that is
#					  ${LOCALBASE}/${SZOPEBASEDIR} by default, 
# ZOPEPRODUCTDIR	- directory, where products for zope can be found
#
# ZOPE_VERSION		- Version of zope that will be used in the port. Set this
#					  in your /etc/make.conf in case you want to use a
#					  specific version of zope.
