// Modified by Uae.  ZorkMUD.  May 21st 1997.

// Try_to_acquire removed from the conditions of drinking
// an object.  drink "" added with fail message "Drink what?".

//  Uae.  May 23rd. 1997.  added:
//  drink_str added.  This is to support drinking from renewable 
//  fluid sources when the fluid_object itself is not present.
//  In your renewable fluid source's id, put "<fluid>_source".
