+FIT
+
+FIT is a program to display data files and to fit standard or user-defined
+functions. It can read many types of data files, mainly neutron scattering
+data. It is extensible for other datafiles types, please ask the author listed
+below how to implement new data files structures. It may also be used as a
+library for automatic fit programs or simply to convert data files.
+The original FIT program was based on an old version of the CERN Minuit
+library. Since 1990, it was extended and improved continuosly.
+There is a built-in help facility, where you can find most of the features
+FIT offers (HELP command).
+For the copyright notice, look at the end of this file.

+Installations instructions
+--------------------------
+
+Various flavors of Unix (Tru64, Linux, Mac OS X):
+
+  for installing fit from source you need the pgplot and readline libraries,
+  if you like nexus support you need also the nexus API, hdf and hdf5
+  and the compilers gcc and g77 (other fortran compilers may need source
+  adjustments)
+
+  Unpack the sources, creating the directory tree ./fitsrc/...
+  and go to the source directory:
+
+  > gunzip fit.tar.gz
+  > tar -xvf fit.tar
+  > rm fit.tar                (assuming you dont want fit.tar as a backup)
+  > cd fitsrc
+
+  Here you can find several system specific makefiles:
+
+  > ls makefile_*
+  makefile_alpha  makefile_alpha_f  makefile_linux  makefile_macosx
+
+  These files are for Tru64 Unix (normal and fast version), RedHat Linux
+  and Mac OS X.
+
+  Edit one of these file to define where the needed libraries are.
+
+  Define an environment variable for your version, for example
+
+  > setenv FIT_VERSION linux
+
+  You may define this also at login.
+
+  Then simply enter
+
+  > make all
+
+  to make all of fit.
+
+  On Linux and Mac OSX systems you should use DEB=D for the debugger
+  friendly, non-optimizing version. The optimized version is buggy.
+  On Tru64 Unix the optimized version is substantially faster.
+
+VMS:
+
+  To build FIT and some related programs execute the CONFIG.COM command
+  file. It will give you further instructions.
+
+
+  Example:
+
+  Let us assume that the sources are in directory [USER.FIT.SRC...]
+  and that the prompt is $
+
+  $ @[USER.FIT.SRC]CONFIG
+  DRA0:[USER.FIT.EXE] created
+  DRA0:[USER.FIT.DEB] created
+  DRA0:[USER.FIT.EXE]MAKE.CFG; created
+  modify this file to define where to find the libraries
+  then use MAKE to make all targets in directory DRA0:[USER.FIT.EXE]
+  or MAKE -D to make a debugger friendly version in directory
+  DRA0:[USER.FIT.DEB].
+  To get some help on the MAKE command type MAKE ?
+
+  $ MAKE
