nevow attempts to use pkg_resources to find the formless css file upon
import, if pkg_resources is available. unfortunately using pkg_resources
to find files is not supported if the files are being loaded from a zip
archive (i.e. only source and egg), and further py2exe uses a zip bundle
for all the code and dependent libraries. hence having both pkg_resources
and nevow built into an exe causes nevow to explode upon import.
this tells py2exe not to link pkg_resources into the target, so that
this behaviour isn't stimulated. the side effect being that pkg_resources
isn't available.
adds windows/depends.py as a container for modules which are needed at runtime
but which py2exe's modulefinder dependency analysis fails to find as requisites.
there are many and various fiddly details that were involved in this process
on mountain view. This is a stripped down version of the build process used
there. there's hence a good chance that one or two necessary details got
stripped down through the cracks.
this provides a py2exe setup.py to build a tahoe.exe and a tahoesvc.exe
the former is equivalent to bin/tahoe, but without the start/stop commands.
the latter is a windows service that instantiates a client whose basedir
is found in the registry.
