/* Do not remove the headers from this file! see /USAGE for more info. */

// Modified by Uae.  May 22nd. 1997.

// Modified to deal with more fluids than water:
// In the fluid_object, add "fluid" to the id.

// Modified to fill fluid containers from renewable sources:
// In the source of the fluid, add "<fluid>_source" to the id.
//  "fill <ob> with <fluid>" will call fill_up( ob ) in the fluid source.
// Use that function to move the relevant fluid to the container.

// May 23rd.  Added functionality for fill_obj_from_obj.
