NAME
asy - Asymptote: a script-based vector graphics language
SYNOPSIS
asy [options] [file ...]
DESCRIPTION
Asymptote is a powerful descriptive vector graphics language for tech-
nical drawings, inspired by MetaPost but with an improved C++-like syn-
tax. 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 in-
put.
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;
