 The environment variables must be defined before `gnuplot` (Note: gnuplot )
 is executed; how to do so depends on your operating system.

       FIT_LOG
 changes the name (and/or path) of the file to which the fit log will be
 written from the default of "fit.log" in the working directory.

       FIT_SCRIPT
 specifies a command that may be executed after an user interrupt. The default
 is `replot` (Note: replot ), but a  `plot` (Note: plot ) or  `load`
 (Note: load ) command may be useful to display a plot customized to
 highlight the progress of the fit.
