<h1 align=center>Description of the program: <font color=Blue>nstep
</font>
</h1>
<hr>
This program makes a local linear ansatz and iterates a artificial
trajectory. The initial values for the trajectory are the last points
of the original time series. Thus it actually forecasts the time series.
<hr>
<h2 align=center>Usage:</h2>
<center>
<font color=Red>nstep [Options]</font>
<p>
Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also <font color=Red>-</font> means stdin
<p>
Possible options are:
