.TH ASY 1 "1 Dec 2004"
.SH NAME
asy \- Asymptote: a script-based vector graphics language
.SH SYNOPSIS
.B asy
.RI [ options ]
.RI [ file \ ...]
.SH DESCRIPTION
\fBAsymptote\fP 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.
.SH OPTIONS
If no arguments are given, Asymptote runs in interactive mode.
.PP
If "\-" is given as the file argument, Asymptote reads from standard input.
.PP
A summary of options is included below. The effect of most options
can be negated by prepending
.B no
to the option name.
Default values for most options may also be entered in the
file
.B .asy/config.asy
in the user's home directory using the long form:
.PP
import settings;
batchView=true;
