FUNCTION

 
NAME
          add_transport  - Add a transport to the system. 


LOCATION
 /std/special/transport/controller 

SYNTAX
 void add_transport(string interior_filename); 

DESCRIPTION
          This function adds a transport to the transport system.
	The argument is the filename to the interior object.
  




FUNCTION
 
NAME
          add_port  - Add a port to the system. 


LOCATION
 /std/special/transport/controller 

SYNTAX
 void add_port(string filename, int x, y, z); 

DESCRIPTION
  	This function adds a port to the transport system at the
	specified coordinates. 
	The first argument is the filename of the port and the 
	other arguments are the coordinates of the port.
	The travel time between the ports are calculated from the 
	coordinates as follows:
	sqrt(x_diff*x_diff + y_diff*y_diff + z_diff*z_diff) seconds.
	(x_diff is the difference in x-coordinates between the ports)
  

  
NOTE
 
	For the most common types of transports the z-coordinate
	can be left out (z=0).
