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;
