KUPLOT is an universal potting program for 2D and 3D data sets on X11 and
TEK4014 screens. The program is controlled by a command language with an 
integrated FORTRAN style interpreter to give maximum flexibility. Some of 
the programs features are listed below:

==============================================================================

The main features of the program include:

-- 2D data plots

      The program supports normal line graphs, marker, error bars as
      well as spline interpolation between the data points. Line color,
      marker color, line type, line width and various other parameters
      can be adjusted. 

-- 3D data plots

      KUPLOT allows to plot 3D data sets using contour lines, colored
      bitmaps or both. The colormap for the bitmap can be freely changed
      using the FORTRAN interpreter (via cmap[] variable). The program
      also allows to define different contour line sets for one data
      set, e.g. finer spaced lines for diffuse scattering and larger 
      space lines in a different color for the Bragg peaks.

-- Function plots & data manipulation

      The FORTRAN style interpreter allows to create data sets from
      a given function. It also opens the possibility for all kinds
      of data manipulation

-- Frames

      KUPLOT allows to divide a page into different plot areas (frame).
      Each frame can contains graphs or the contents of a text file.
      Frames can have different background colors. Each frame has its
      own parameter set like title, axis labels, fonts, etc..

-- Least square fitting

      KUPLOT has an integrated FIT sublevel, which allows to fit the
      following functions to a given data set: polynom, n Gaussian(s)
      and n Lorenzians. 3D data sets can be fitted using a set of
      2D Gaussians.

-- Output generated

      The program can produce hardcopies in POSTSCRIPT (incl. color)
      and HPGL format. Additionally, read data sets can be saved in 
      various formats including PGM. PGM is a fileformat used by the
      'pbmplus' package which provides tools to convert PGM file into
      (nearly) any other graphics format.

-- Command language

      The program uses a command language to interact with the user.
      No predefined requirement exists for a given sequence of commands.
      The commands can be typed at the KUPLOT prompt, or read from a
      macro file. Macro files may be written by any editor or learned
      during execution.

-- Build in FORTRAN interpreter

      The command language includes a FORTRAN style interpreter that
      allows the user to program loops and logical structures.
      Several real and integer variables as well as structural variables
      can be used to design the intended defect structure.

      You can use the interpreter to modify individual atoms ans thus
      generate any desired defect structure. See the examples on the WWW
      page for some applications.

-- File names

      A special feature of the FORTRAN interpreter is an automatic 
      file name generation process. This allows you to perform multiple
      simulations that can all be saved under individual names.

-- On-line help

      On line help is provided which gives the user information on any of the 
      KUPLOT commands as well as examples for typical KUPLOT sessions.

-- Error Messages

      The program generates error messages for (hopefully) all erroneous 
      situations that should provide enough information to the user in
      order to correct the errors that have occurred.

-- Manual & Tutorial

      The program comes with a detailed manual, HTML version of the online
      help and a tutorial macro package to get started with the use of
      KUPLOT.

===============================================================================

The program is written in standard Fortran-77 and can easily be adapted 
to any specific Fortran compiler.
The program has been installed on several different platforms:

     SUN-workstations 
     HP -workstations 
     LINUX
     VMS (VAX and ALPHA)
     MS-DOS
