[Help-gnucap] quiet mode?

[dan chak]

Is there a quiet mode in gnucap?  I am running it in batch mode from 
another program, and I don't want all the constant output in the 
terminal.  I could redirect my entire program to /dev/null, but I don't 
really want to do that, and I don't know if it's possible to redirect 
the output of an execl() call...

I'm looking for something of the form "gnucap --quiet -b".. Also, is 
there really a reason for output at all when in batch mode, except for 
maybe errors?

Another weird thing I noticed about batch mode is that the user is 
prompted to replace output files.  By being called "batch mode" I assume 
this to mean there is no user present to provide intervention, so I 
would expect it to just proceed by overwriting the file that's present.

thanks,
