|  plot_letter -- plot a letter from 2 floating-point arrays	|
|								|
|  Ajaipal S. Virdy, Entropic Processing, Inc. 			|
|								|
|  Module:	plot_letter.c					|
|								|
|  Given arrays of x- and y-coordinates, plot_letter writes plot|
|  commands in ``Stanford'' plotas input format to plot the	|
|  line connecting the points with the given coordinates.  The	|
|  argument len is the number of points to plot; xmin ... ymax	|
|  are the data coordinates that are to correspond to the	|
|  edges of the plot.						|
