You can specify details regarding the deals that GIB produces. To do this, simply go to the ``custom deal type'' item of the setup menu. For each player and each attribute (length in a particular suit, or total HCP), you can select both an upper and a lower limit. Initially, the limits are 0-13 for length in each suit and 0-40 for HCP, meaning that any deal at all is acceptable. To change the upper or lower limit, click on the entry and then adjust it.
