What is a preset?
A preset is a set of values for the different parameters that can be changed in Game Courier. The parameters control such things as board size and shape, piece positions, graphics used for boards and pieces, methods for rendering diagrams, and code for automating complicated moves or for enforcing rules. In brief, a preset is a set of parameters that define a particular game with a particular appearance. A preset is normally expressed as a set of default values and changes to the defaults.
