Update to version 4.2:
Changes from 4.1.2 to 4.2
1) Added support for Python 2.7.
2) Improved support for Python 3.x.
3) Improved support for Mac OS X based on feedback from some Mac users.
4) Improved hooks for the following modules: postgresql, matplotlib, twisted,
zope, PyQt4.
5) Improved packaging of MSI files by enabling support for creating shortcuts
for the executables, for specifying the initial target directory and for
adding other arbitrary configuration to the MSI.
6) Added support for namespace packages such as those distributed for zope.
7) The name of the generated MSI packages now includes the architecture in
order to differentiate between 32-bit and 64-bit builds.
8) Removed use of LINKFORSHARED on the Mac which is not necessary and for
Python 2.6 at least causes an error to be raised.
9) Turn off filename globbing on Windows as requested by Craig McQueen.
10) Fixed bug that prevented hooks from successfully including files in the
build (as is done for the matplotlib sample).
11) Fixed bug that prevented submodules from being included in the build if the
format of the import statement was from . import <name>.
12) Reverted bug fix for threading shutdown support which has been fixed
differently and is no longer required in Python 2.6.5 and up (in fact an
error is raised if the threading module is used in a frozen executable and
this code is retained).
13) Fixed bug which resulted in attempts to compile .pyc and .pyo files from
the initscripts directory.
14) Fixed selection of "Program Files" directory on Windows in 64-bit MSI
packages built by cx_Freeze.

Log message:
Import cx_Freeze-4.1.2nb1 as wip/cxfreeze.

cx_Freeze is a set of scripts and modules for freezing Python scripts into
executables in much the same way that py2exe and py2app do. Unlike these
two tools, cx_Freeze is cross platform and should work on any platform that
Python itself works on.
