Why is this needed?

I agree that it's the best approach, lacking "cvs copy". It would be bad to
loose all history on all files.

I haven't seen any.

An excellent ocasion to restructure "new". Here is the list of new directories
for all staff in "new", in my opinion. Comments are welcome.

alias.jam build
assert.jam util
boost-build.jam ??? maybe just remove
build-request.jam build
builtin.jam tools
class.jam kernel
common.jam tools
container.jam util
doc.jam util
feature.jam build
generators.jam build
indirect.jam util
make.jam tools
modifiers.jam build
numbers.jam util
os.jam util
path.jam util
prebuilt.jam tools
print.jam util
project-roots.jam build
project.jam build
property-set.jam build
property.jam build
regex.jam util
scanner.jam build
sequence.jam util
set.jam util
site-config.jam build?
stage.jam tools
string.jam util
symlink.jam tools
targets.jam build
test.jam build?
testing.jam tools
toolset.jam build
type.jam build
user-config.jam build?
utility.jam util
version.jam build
virtual-target.jam build
readme.txt build

Besides, I have one idea: I recall SF provides CVS snapshots. We can get one,
run your script and check if the results are OK. I'm about to download it
now, not sure how much it will take ;-)
