I've also set up a new flappserver on source@allmydata.org to receive the

tarballs used to be generated+uploaded) and give it the new FURL.
docs: remove obsolete doc file "codemap.txt"

Simplify immutable download API: use just filenode.read(consumer, offset, size)

webapi: use t=mkdir-with-children instead of a children= arg to t=mkdir .
This is safer: in the earlier API, an old webapi server would silently ignore
the initial children, and clients trying to set them would have to fetch the
newly-created directory to discover the incompatibility. In the new API,
clients using t=mkdir-with-children against an old webapi server will get a
clear error.

setup: remove binary WinFUSE modules
I would prefer to have just source code, or indications of what 3rd-party packages are required, under revision control, and have the build process generate o

setup: remove a convenience copy of figleaf, to ease inclusion into Ubuntu Karmic Koala
We need to carefully document the licence of figleaf in order to get Tahoe-LAFS into Ubuntu Karmic Koala. However, figleaf isn't really a part of Tahoe-LAFS per se -- this is just a "convenience copy" of a development tool. The quickest way to make Tahoe-LAFS acceptable for Karmic then, is to remove figleaf from the Tahoe-LAFS tarball itself. People who want to run figleaf on Tahoe-LAFS (as everyone should want) can install figleaf themselves. I haven't tested this -- there may be incompatibilities between upstream figleaf and the copy that we had here...
