Class description
Instance of this class is used as database configuration object. It has following slots:

block-size	The size of a single transfer from disk to memory. If the value is less than 512, the file system blocksize is used (this is default).
role	Determines what kind of access the user wants to obtain (see below).
sync	Being set to t causes all database operations to be synchronized to the disk.
nolock	Being set to t prevents gdbm from performing any locking on the database file.
mode	An integer representing standard UNIX access permissions.

The role can be set to one of the folowing values:

reader	The user can only read from existing database.
writer	The user can access existing database as reader and writer.
wrcreat	Open the database for reading and writing if it exists and create new one otherwise.
newdb	Create empty database even if there is already one with the same name.
