XYL_DISPLAY_OPENGL is a C++ program which reads XYL information defining points and lines in 2D, and draws a picture using OPENGL.
The point and line information is stored in a pair of files, called the XYL format. Essentially, the first file stores a list of point coordinates, and the second lists point indices to be connected in lines.
