asy - Asymptote: a script-based vector graphics language
Asymptote is a powerful descriptive vector graphics
language for technical drawings, inspired by MetaPost but with an improved
C++-like syntax. Asymptote provides for figures the same high-quality level
of typesetting that LaTeX does for scientific text.
If no arguments are given, Asymptote runs in interactive mode.
If "-" is given as the file argument, Asymptote reads
from standard input.
A summary of options is included below. The effect of most options
can be negated by prepending no to the option name. Default values
for most options may also be entered in the file .asy/config.asy in
the user's home directory using the long form:
import settings;
batchView=true;

Asymptote is documented fully in the asymptote Info page. The
manual can also be accessed in interactive mode with the "help"
command.
Asymptote was written by Andy Hammerlindl, John Bowman, and Tom
Prince.
