-
-   If you set a maximum for the number of documents in a capped
-   collection, the maximum must be less than 2^32. You *cannot* set a
-   higher maximum. Alternatively, you can choose *not* to set a maximum,
-   in which case the number of documents can exceed 2^32.
-
-   You specify the maximum when creating a capped collection by setting
-   the optional ``max`` parameter. For details, see
-   :method:`db.createCollection()` or :dbcommand:`create`.
