Add bsd.python.mk. This file contains definitions which hopefully

make dealing with Python-related ports easier.

This needs to be activated from bsd.ports.mk; Satoshi will do that later.

+# 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), but not using the full path.
+#				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: ${LOCALBASE}/lib/python${PYVERSION}
+#
+# PYTHON_PORTSDIR:	The source of your binary's port. Needed for the
+#					RUN_DEPENDS.
+#
+# PYTHON_PORTVERSION:	Version number suitable for ${PORTVERSION}.
+#
+# PYTHON_SITELIBDIR:	Location of the site-packages tree. Don't change,
+#					unless you know what you do.
+#						default: ${PYTHON_LIBDIR}/site-packages
+#
+# 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.
