When in \s-1UCI\s0 mode PolyGlot mostly passes commands from the \s-1GUI\s0
to the engine and vice versa, except that it will play book moves on
behalf of the engine when the occasion arises.
+.PP
+The engine options are exported as \s-1UCI\s0 options in \s-1UCI\s0
+mode and as \*(L"feature option=\*(R" commands in xboard mode. The latter form
+an extension of the xboard protocol as defined by H.G. Muller.
+.PP
+Options which normally appear in the [PolyGlot] section of the
+config file (see below) are exported as options with their name prefixed
+by \*(L"Polyglot\*(R". This makes it easy to filter them in the \s-1GUI\s0.
+.PP
+\&\s-1NOTE:\s0 Not all options are exported, only those that make sense in the
+given mode.

PolyGlot supports the \*(L"PolyGlot opening book format\*(R". This is the
default config file is \*(L"polyglot.ini\*(R".

When invoked as
+.Sh "polyglot \-ec engine"
+.IX Subsection "polyglot -ec engine"
+PolyGlot simply starts \*(L"engine\*(R" and acts as an adapter. No config file
+is used and thus it is expected that all properties will be set by the
+\&\s-1GUI\s0.
