NAME
     troff - description of output language

DESCRIPTION
     Output from troff is pure ASCII written in the following language:

     sn            Use point size n.

     fn            Use the font mounted at position n.

     cx            Print ASCII character x at the current position.

     Cxy           Print special character xy at the current position.

     Hn            Absolute horizontal move to position n.

     hn            Relative horizontal move of n units.

     Vn            Absolute vertical move to position n (down is positive).

     vn            Relative vertical move of n units.

     nnx           Move nn units horizontally then print ASCII character x.

     nb a          End of a line.

     pn            Begin page n.

     # ...         Comment - to the end of the line.

     Dl dx dy      Line from current point (x, y) to point (x+dx, y+dy).

     Dc d          Circle of diameter d with left side at the current
                   point.

     De dx dy      Ellipse with axes dx and dy and left side at the current
                   point.

     Da dx1 dy1 dx2 dy2
                   Counterclockwise arc from current point (x, y) to
                   (x+dx1+dx2, y+dy1+dy2). Center of the circle is (x+dx1,
                   y+dy1).

     D~ dx1 dy1 dx2 dy2 ...
                   B-spline from current point (x, y) to (x+dx1, y+dy1),
                   then to (x+dx1+dx2, y+dy1+dy2).

     x init        Initialize the typesetter.

     x T device    The name of the typesetter is device.

     x res n h v   The resolution of the typesetting device in increments
                   per inch is n. Motion in the horizontal direction can
                   take place in units of h basic increments. Motion in the
                   vertical direction can take place in units of v basic
                   increments.

     x stop        Stop - done forever.

     x trailer     Generate a trailer.

     x font n name Mount font name at position n.

     x Height n    Set character height to n points.

     x Slant n     Set character slant to n degrees.
