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;

       For a complete description, see the Info files.
