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.
this is probably not of very high utility in the unix case of bin/tahoe
but is useful when working with native builds, e.g. py2exe's tahoe.exe,
to examine and debug the runtime environment, linking problems etc.
py2exe is unable to handle .eggs which are packaged as zip files
in preference it will pull in other versions of libraries if they
can be found in the environment.
this changes causes .eggs to be built as .egg directories, which
py2exe can handle.
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.
Technically, we could get away with v0.6c5 or v0.6c4 on non-cygwin platforms, but if someone currently doesn't have setuptools >= v0.6c6 installed then our setup process will just use our bundled setuptools v0.6c7 anyway, so it will still work, and this makes the setup.py and the accompanying documentation simpler.
For simplicity, and to avoid weird failure modes that result from importing nevow during the build process, we now simply require nevow >= 0.6.0. We currently bundle in misc/dependencies nevow v0.9.18, which will not work on Dapper, since it requires Twisted >= 2.4.0, and Dapper comes with Twisted 2.2.0. Dapper users can (a) install a newer Twisted, (b) install nevow 0.6.0 in egg form so that setuptools can tell that it is installed (without importing it), (c) beg us to start shipping nevow 0.6.0 instead of nevow 0.9.18 in our bundle.
a recent purge of the start.html code also took away the logic that wrote
'node.url' into the node root. this is required for the tahoe cli tool to
find the node. this puts back a limited fraction of that code, so that the
node writes out a node.url file upon startup.
