showing commands sent from GSView to Ghostscript

Hi,
I am performing some conversions from postscript to png using 
GSView (v4.16). I presume that this program uses Ghostscript 
(v8.14) for the actual conversions. Is there a way to see what 
'command line' is sent to Ghostscript for the conversions? I would 
like to eventually use a batch script to do the conversion, so it 
would be nice to have this information. These commands don't show 
up in 'Show Messages'.

Thanks.
