# 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: ${LOCALBASE}/bin/${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_INCLUDEDIR:    Location of the Python include files.
#                       default: ${LOCALBASE}/include/${PYTHON_VERSION}
#
# PYTHON_LIBDIR:    Base of the python library tree
#                   default: ${LOCALBASE}/lib/${PYTHON_VERSION}
#
# PYTHON_PKGNAMEPREFIX: Use this as a ${PKGNAMEPREFIX} to distinguish
#                       packages for different Python versions.
#                       default: py${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.
#
# 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.
