quick render commandline

Hi,

I notice there is a freefreemarker.core.CommandLine class, which just
print FM version. It would be nice to also accept template file as
argument and process them with just empty model. This can provide
quick testing.

Just a simple thing like this will help:

public static void main(String[] args) {
			if(args.length>0){
				Configuration cfg = new Configuration();
				Template template = cfg.getTemplate(args[0]);
				java.io.Writer out = new OutputStreamWriter(System.out);
				template.process(new java.util.HashMap(), out);
			}else{
        System.out.println();
        System.out.print("FreeMarker version ");
        System.out.println(Configuration.getVersionNumber());
        System.out.println();
        System.out.println("Copyright (c) 2003 The Visigoth Software Society.");
        System.out.println("All rights reserved.");
        System.out.println();
        System.out.println("This is Free software. Please read the
LICENSE.txt comes with ");
        System.out.println("the distribution for more details.");
        System.out.println();
        System.out.println("For more information and for updates visit
our WWW site:");
        System.out.println("http://freemarker.org/");
        System.out.println();
			}
    }
