Embed git in package
package.ps1 fetches PortableGit and embeds it in the package. This eliminates all but one runtime dependency (MSVC++ Redistributable). * Move Python into a new FOSS folder.

+"""
+This module is designed to be used as follows::
+
+ from future.builtins.iterators import *
+
+And then, for example::
+
+ for i in range(10**15):
+ pass
+
+ for (a, b) in zip(range(10**15), range(-10**15, 0)):
+ pass
+
+Note that this is standard Python 3 code, plus some imports that do
+nothing on Python 3.
+
+The iterators this brings in are::
+
+- ``range``
+- ``filter``
+- ``map``
+- ``zip``
+
+On Python 2, ``range`` is a pure-Python backport of Python 3's ``range``
+iterator with slicing support. The other iterators (``filter``, ``map``,
+``zip``) are from the ``itertools`` module on Python 2. On Python 3 these
+are available in the module namespace but not exported for * imports via
+__all__ (zero no namespace pollution).
+
+Note that these are also available in the standard library
+``future_builtins`` module on Python 2 -- but not Python 3, so using
+the standard library version is not portable, nor anywhere near complete.
