NAME
asy - Asymptote: a script-based vector graphics language
SYNOPSIS
asy [options] [file ...]
DESCRIPTION
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.
OPTIONS
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;
