You have to read the source code.

Here's a Java program I wrote that talks to the server:
It reads lines from stdin and sends them to the server.

import java.io.*;
import java.net.*;

public class GimpClient {
    public static void main(String args[]) throws IOException {
	Socket sock;
	DataInputStream dis;
	PrintStream dat;
	byte[] header = new byte[2];
	byte[] reply = new byte[99];
	InputStreamReader is = new InputStreamReader(System.in);
	BufferedReader br = new BufferedReader(is);

	sock = new Socket("localhost",10008);

	dis = new DataInputStream(sock.getInputStream());
	dat = new PrintStream( sock.getOutputStream());
	
	for(;;){
	    String myline = br.readLine();
	    if (myline == null) break;
	    header[0] = (byte) (myline.length()>>8);
	    header[1] = (byte) (myline.length() % 256);
	    dat.print("G"+new String(header)+myline);
	    dat.flush();
	    int len = dis.read(reply);
	    for (int i = 0; i < len; i++){
		System.out.print((char)reply[i]);
	    }
	    System.out.println();
	    
	}

	sock.close();
    }
}
