# 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.
#
# The variables:
#
# PYTHON_CMD:	Python's command line file name, including the version
#				number (used for dependencies).
#				default: depends on the version of your python binary
#
# 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_LIBDIR:	Base of the python library tree
#					default: ${LOCALBASE}/lib/python${PYTHON_VERSION}
#
# PYTHON_PKGNAMEPREFIX:	Use this as a ${PKGNAMEPREFIX} to distinguish
#						packages for different Python versions.
#						default: py${PYTHON_SUFFIX}-
#
# 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.
#
# PYDISTUTILS:	Dependency line for the distutils extension. As of Python-2.0,
#				the distutils are in the base distribution.
#
# PYXML:		Dependency line for the XML entension. As of Python-2.0,
#				this extension is in the base distribution.

# XXX Ugly hack, but running python is the best way to determine the
# currently installed version. If Python is not installed, a default 
# version number is substituted and the corresponding Python distribution
# will be built through the dependency processing.
