 Asymptote is a powerful script-based vector graphics language that
 provides a natural coordinate-based framework for technical drawing.
 Labels and equations are typeset with LaTeX, for high-quality
 PostScript output.
 
 A major advantage of Asymptote over other graphics packages is that
 it is a programming language, as opposed to just a graphics program:
 it can therefore exploit the best features of script (command-driven)
 and graphical user interface (GUI) methods.
