PROGRAM
     vsurf - Compute surface parameters (normal and angle)

SYNTAX
     vsurf

     -i             input image

     -norm          normals image

     -ang           angles image

     [-V]           Gives the version for vsurf

     [-U]           Gives the usage for vsurf

     [-P]           Prompts for command line options

     [-A [file1]]   Creates the answer file called vsurf.ans or
                    file1

     [-a [file1]]   Uses vsurf.ans or file1 as the answer file

DESCRIPTION
     vsurf will take a surface image and produce two output
     images: one with the normals for each point on the surface
     and one with the angle between the surface normal and the
     normal to the zero plane of the image.

     The angle output image is in degrees.

REQUIRED ARGUMENTS
     -i     type: infile
            desc: input image

     -norm  type: outfile
            desc: normals image

     -ang   type: outfile
            desc: angles image

OPTIONAL ARGUMENTS
     none

EXAMPLES
     % vsurf -i surface -norm normals -ang angles
