val to_dot : Format.formatter -> Core.Term.sym -> unit

to_dot ppf sym prints a dot graphviz representation of the tree of symbol sym on ppf. Each node of the tree embodies a pattern matrix. The label of a node is the column index in the matrix on which the matching is performed to give birth to the child node. The label on the edge between a node and one of its children represents the term matched to generate the next pattern matrix (the one of the child node).
