=head1 DESCRIPTION
|
|
|
|
The B<engine> command is used to query the status and capabilities
|
|
of the specified B<engine>'s.
|
|
Engines may be speicifed before and after all other command-line flags.
|
|
Only those specified are queried.
|

=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-v> B<-vv> B<-vvv> B<-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.
|
|
|
|
=item B<-c>
|
|
|
|
Lists the capabilities of each engine.
|
|
|
|
=item B<-t>
|
|
|
|
Tests if each specified engine is available, and displays the answer.
|
|
|
|
=item B<-tt>
|
|
|
|
Displays an error trace for any unavailable engine.
|
|
|
|
=item B<-pre> I<command>
|
|
=item B<-post> I<command>
|
|
|
|
Command-line configuration of engines.
|
|
The B<-pre> command is given to the engine before it is loaded and
|
|
the B<-post> command is given after the engine is loaded.
|
|
The I<command> is of the form I<cmd:val> where I<cmd> is the command,
|
|
and I<val> is the value for the command.
|
|
See the example below.
