 ******** What is FUDGIT? ********

 FUDGIT is a double-precision multi-purpose fitting program.
 It can manipulate complete columns of numbers in the form
 of vector arithmetic. FUDGIT is also an expression language
 interpreter understanding most of C grammar except pointers.
 Morever, FUDGIT is a front end for any plotting program supporting
 commands from stdin. It is a nice mathematical complement to
 GNUPLOT, for example.

 The main features of FUDGIT are:
    - Built-in fitting series such as:
        + power series (polynomial);
        + sine series;
        + cosine series;
        + Legendre polynomials;
        + series of Gaussians;
        + series of exponentials;
    - User definable fitting functions;
    - Fourier transforms;
    - Spline interpolation;
    - Smoothing;
    - Double-precision built-in calculator;
    - Built-in interpreter supporting most of C language including
      flow control (if, else, while, for, break, continue);
    - User definable functions and procedures;
    - Double-precision vector arithmetic;
    - Access to the complete C math library;
    - Possible abbreviation of all the ``fitting mode'' commands;
    - Possible plural when it makes sense too;
    - Interactive shell supporting flow control (while,
      if-else-endif, foreach);
    - User definable macros;
    - User definable aliases;
    - On-line help;
    - On-line loadable procedure- or function-objects;
    - Totally dynamical allocation of variables and parameters;
    - Possible selection of fitting ranges;

 FUDGIT has a collection of fitting routines including:
    - straight line (linear) least squares;
    - straight line (linear) least absolute deviation;
    - general linear least squares using QR decomposition;
    - general linear least squares using singular value decomposition;
    - nonlinear Marquardt-Levenberg method;

 tutorial on I/O and fitting.
