setting name for screenshots

[John Sturdy <john sturdy ul ie>]

Hi,

I'm doing something that involves taking a series of screenshots
automatically. Is there some way to get gnome-panel-screenshot to
accept the name on the command line (or via an environment variable,
or whatever), and not ask the user about it?

Or is there some way to do this with some other (command-line)
utility?
