+Welcome to GNUFIT - an extension to GNUPLOT
+===========================================
+
+Version 1.2
+
+gnuplot has been widely established as a powerful tool to do data and
+function plots. For the scientific use one additionally often needs
+a nonlinear least squares fitting procedure to combine a model function
+to measured data. This is introduced by GNUFIT. GNUFIT is a real extension
+of GNUPLOT that means, it covers all features of GNUPLOT and adds some new
+ones.
+
+GNUFIT incorporates a nonlinear least squares fit mechanism into GNUPLOT. The
+fit uses the Marquardt-Levenberg-algorithm for fitting and the GNUPLOT
+function evaluation mechanism for calculation. Thus it remains relatively
+small. It offers all advantages of fitting every rather complex-formulated
+function you can create with GNUPLOT (including complex calculation).
+
+
+GNUFIT is available as follows:
+
+ gnufit12.tar.gz All new sources and diff's against gnuplot3.4 and
+ gnuplot3.5, readmes, demos and installation hints
+ needed to compile and run GNUFIT on your machine,
+ provided that you already have the original
+ gnuplot sources.
+
+ gft12dos.zip DOS executables
+
+
+A description of the files in gnufit12.tar.gz
+=================================================
+
+readme.1st This file - Overview
+compile.fit Some hints for the compilation on various platforms
+install UNIX shellscript to do the patches
+install.bat DOS Batchfile for the same purpose
+credits A list of people who helped me making GNUFIT stable
+
+fit.c the main fitting routines
+fit.h Interface to fit.c
+matrix.c some matrix algebra needed in fit.c
+matrix.h interface to matrix.c
+type.h commonly used types
+linux.trm terminal driver for LINUX
+
+patches.35 Context diff's of the GNUFIT sources against the GNUPLOT3.5
+ sources. They have been done using
+ diff -cr oldfile newfile >> patches.35
+ and may be applied to the gnuplot sources by the patch program.
+ This is done also by the install-script.
+patches.34 Same story based on gnuplot3.4 for the case of incompatibilities
+
+
+
+Installation procedure:
+=======================
+
+
+1) Start from the directory */diff which has been generated by untaring
+ this package.
+
+2) Create a directory (e.g. called 'gnufit') and place a copy of the gnuplot3.2
+ sources (including the subdirs) in it. Make sure that it is writable.
+ gnuplot sources may be obtained from ftp.dartmouth.edu in
+ /pub/gnuplot
+
+3) If you're not working under DOS or UNIX, create an appropriate
+ scriptfile like has been done in 'install' (UNIX) or 'install.bat' (DOS).
+ The only commandline-parameter of the scriptfile is the directory you
+ just created (gnufit).
+
+4) Execute the scriptfile. This will copy the necessary sources to 'gnufit'
+ and do the needed patches to the gnuplot sources. Finally it changes
+ the actual working directory.
+
+ e.g. install ~/gnufit
+
+5) Look at the file 'compile.fit' for compilation hints on your system.
+ That may require small changes to the appropriate makefile, e.g. for
+ compiler selection and compiler switches.
+
+6) Check the compilation hints for gnuplot in 'readme.ins' and execute them.
+
+GNUFIT has been successfully tested and compiled on the following
+operating systems:
+
+ DOS (MSC 6.0), OS/2, SunOS, HPUX, IBM/RS6000, DEC Ultrix, DG/UX, LINUX
+ Amiga
+
+Only the compilers mentioned in 'compile.fit' have been used.
+For compatibility purposes with other scripts written for GNUPLOT, the
+executables' filenames are still left 'gnuplot', 'gnuplot.exe' etc.
+The starting message however distinguishes between GNUPLOT and GNUFIT.
+To get a successful compilation on other systems there may be minor patches
+to the sources necessary. If you succeed in adding a new platform, please
+generate diff's of the modified sources and send them to me. They may be
+included into a further release of GNUFIT.
+
+
+
+What is planned?
+================
+
+This will probably be the last release of GNUFIT. Not because I think it's
+rubbish but because it will be included as an internal part into the next
+official release of gnuplot. Development is under way!
+
+Please send any comments, bug-reports, implementation reports and
+improvement proposals to gnuplot-bugs@lists.sourceforge.net
