I guess I should restate that I very much appreciate this feature.
To release the burden on a developer for creating a new file in the
project, this feature would allow the system to automatically detect
that a new file is added (the developer thus does not have to add it
into some variable in some jamfile) and I can automatically in jam also
add it to the CVS : it's all about automation (which is the reason we
have computers right ?)
