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;
