PIC(1)                                                     PIC(1)

     NAME
          pic - troff preprocessor for drawing pictures

     SYNOPSIS
          pic [ -Tt ] [ -D ] [ files ]

     DESCRIPTION
          Pic is a troff(1) preprocessor for drawing figures on a
          typesetter.  The basic objects are box, line, arrow, spline,
          circle, ellipse, arc, and text.  These may be positioned in
          absolute coordinates or relative to previously placed
          objects.  Pic also provides blocks, variables, expressions,
          built-in functions, loops, conditionals, and a macro proces-
          sor.

          The optional argument -Tt specifies typesetter t; currently
          supported typesetters are 202 (the default), cat (Graphic
          Systems CAT), and aps (Autologic APS-5).

          The argument -D causes pic to generate troff commands that
          draw lines of higher quality.  Recommended for final copy on
          typesetters.
