The \fBengine\fR command is used to query the status and capabilities
of the specified \fBengine\fR's.
Engines may be specified before and after all other command-line flags.
Only those specified are queried.

.IX Item "-v -vv -vvv -vvvv"
Provides information about each specified engine. The first flag lists
all the possible run-time control commands; the second adds a
description of each command; the third adds the input flags, and the
final option adds the internal input flags.
.IP "\fB\-c\fR" 4

Lists the capabilities of each engine.
.IP "\fB\-t\fR" 4
.IX Item "-t"
Tests if each specified engine is available, and displays the answer.

.PD
Command-line configuration of engines.
The \fB\-pre\fR command is given to the engine before it is loaded and
the \fB\-post\fR command is given after the engine is loaded.
The \fIcommand\fR is of the form \fIcmd:val\fR where \fIcmd\fR is the command,
and \fIval\fR is the value for the command.
See the example below.
