The <code>uninitialized</code> integer contains one bit set to one for each

initialization function which has not been called. It becomes equal

to zero after all initialization functions have been called. The

struct is then initialized and <code>provided == true</code>.
|
|
Some values are initialized by default, and are not concerned by

this mechanism.

the dependencies are more recent than the date of the data to
