*  NAME
*     SPR_Type -- Spooling rule
*
*  ELEMENTS
*     SGE_STRING(SPR_name, CULL_HASH | CULL_UNIQUE)
*        Unique name of the rule.
*
*     SGE_STRING(SPR_url, CULL_DEFAULT)
*        An url, e.g. a spool directory, a database url etc.
*
*     SGE_REF(SPR_option_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a function to set any database specific options, 
*        e.g. whether to do database recovery at startup or not.
*
*     SGE_REF(SPR_startup_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a startup function, 
*        e.g. establishing a connection to a database.        
*
*     SGE_REF(SPR_shutdown_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a shutdown function,
*        e.g. disconnecting from a database or closing file handles.
*
*     SGE_REF(SPR_maintenance_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a maintenance function for 
*           - creating the database tables / directories in case of 
*             filebased spooling
*           - switching between spooling with/without history
*           - backup
*           - cleaning up / compressing database
*           - etc.
*
*     SGE_REF(SPR_trigger_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a trigger function.
*        A trigger function is used to trigger regular actions, e.g.
*        checkpointing and cleaning the transaction log in case of the
*        Berkeley DB or vacuuming in case of PostgreSQL.
*
*     SGE_REF(SPR_transaction_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        function pointer to a function beginning and ending transactions.
*
*     SGE_REF(SPR_list_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function reading complete lists (master lists)
*        from the spooling data source.
*
*     SGE_REF(SPR_read_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function reading a single object from the
*        spooling data source.
*
*     SGE_REF(SPR_write_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function writing a single object.
*
*     SGE_REF(SPR_delete_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function deleting a single object.
*
*     SGE_REF(SPR_validate_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function validating a single object.
*
*     SGE_REF(SPR_validate_list_func, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        pointer to a function validating a list of objects.
*
*     SGE_REF(SPR_clientdata, CULL_ANY_SUBTYPE, CULL_DEFAULT)
*        clientdata; any pointer, can be used to store and
*        reference rule specific data, e.g. file or database handles.
*
*  FUNCTION
*     A spooling rule describes a certain way to store and retrieve
*     data from a defined storage facility.
*     
*     Spooling rules can implement spooling to files in a certain
*     directory or spooling into a database, to an LDAP repository
*     etc.
*  
*     A spooling context can contain multiple spooling rules.
