+function graphToDot(adj, varargin)
+% GRAPHTODOT Makes a GraphViz (AT&T) ile representing  an adjacency matrix
+% function graphToDot(adj, ...)
+% Optional arguments should be passed as name/value pairs [default]
+%
+% 'filename' - if omitted, writes to 'tmp.dot'
+% 'arc_label' - arc_label{i,j} is a string attached to the i-j arc [""]
+% 'node_label' - node_label{i} is a string attached to the node i ["i"]
+% 'width'     - width in inches [10]
+% 'height'    - height in inches [10]
+% 'leftright' - 1 means layout left-to-right, 0 means top-to-bottom [0]
+% 'directed'  - 1 means use directed arcs, 0 means undirected [1]
+%
