Comment 4 for bug 524162

The linked branch has my progress so far on this, namely migrating the setup.py py2exe logic (from bzr's setup.py) to a new script/class in the Windows Installer project. That script/class needs to be hooked in and tested. I'm hoping John can have a go at that in the coming hours as I need to sleep now.

FWIW, I've also started work on migrating build-installer.bat.in to build-installer.py.in: I find the bat script template very hard to change and debug. Again it's yet to be tested and debugged but it may help get this (and follow-on improvements) working sooner.
