Starting Fen2eps is as simple as saying
fen2eps < a.fen > a.eps
where the file `a.fen' contains a single FEN
string in one line and
`a.eps' is the resulting EPS file.
This EPS file contains all necessary graphic symbols
for displaying the chess diagram, you don't have to install any fonts!
Since Fen2eps reads each line only to the first "space"
character you can also input EPD (Extended Position Description) strings...
If you call Fen2eps with one of the command-line arguments ``-h'',
``-?'' or ``--help'', a small usage message appears.
It provides a short overview of the additional options, which are explained
in detail in the following sections.
