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;
