[Numpy-discussion] Compiling for free on Windows32

As I said before we have a very big set up. The problem is not the
difficulty in making eggs. Eggs are very easy things to make if you can
make the C++ compile first. 

Setuptools is a very good and stable project whose purpose is to help
automate very large deployments of Python dependancies. Your .exe
approach is not a solution. Let me explain why.

In a bank, every bit of software we run has to be certified by the
relevant auhtorities. That means one project might require numpy 1.3.0.1
weheras another might require 1.1.1. We are not authorized to run any
combination of dependancies that is not certified. But some projects
that need to run on the same grid might have different Numpy
dependancies.

We need to be able to run both projects concurrently on the same grid.
Setuptools + eggs allows this to happen. If we used .exe installers then
we could only have one single version of any given dependancy at any
time and so we would not be able to run the two projects in paralell.

In summary: 

.exe files are fine for single-users and simple deployments but not
suitable for very big deployments. Eggs may not be perfect but they are
by far the best soltion we have.

I think having a simple .exe installer that easy_install could run would
be enough for your purpose (handling install_require dependencies). In
that case, you just need to extract the arch specific installer from our
official installer (the superpack .exe is compressed with 7zip), choose
the most appropriate installer, and add this on your server. I think
easy_install should then be able to automatically use the .exe to handle
dependencies,
