This section describes how to pause, start, or stop the engine (bfengine.exe / bfengine.pl).
Note: If you have any problems getting the engine to run, run it
in the foreground so that you can see the status and error messages it generates.
On Windows, select to run the engine in the foreground,
which causes it to display output in a console window. When the engine is
running in the foreground, you can stop it by closing its console window.
