+SYNOPSIS:
+    string object_name()
+    string object_name(object ob)
+
+DESCRIPTION:
+    Get the file name of an object or if no argument is given of the current
+    object. If the object is a cloned object, then it will not have a
+    corresponding file name, but rather a new name based on the original
+    file name.
+        
+    The returned name always begins with '/' (absolute path),
+  	except when the parser runs in COMPAT (-o) mode.
+
+EXAMPLES:
+    find_object(object_name(ob)) == ob    
+    This is guaranteed to be true for all objects ob that are not
+   	destructed.
+        
+    sizeof(explode(object_name(ob), "#")) == 1  
+    This is always true if ob is a blue print.
+

+        find_object(E)
