FUNCTION

NAME
        inherit - inherit the functions and variables of another object


SYNTAX
	inherit "filename";

DESCRIPTION
	This is not a function in the normal manner, but merely a way to make
	all functions and variables from an object available to your object
	without copying it entirely.

	The filename counts from the root and not, like the include statement,
	from the current directory. If you wish to make a function with the
	same name as one in the inherited object you can still access the
	inherited one using two colons in front of the function name:
	reset(arg)
	{
	  ::reset(arg);
	This will call reset(arg) in the inherited object.

	If you inherit more than one file you reach the functions in them by
	prepending the filename before '::' :
	inherit "/std/simple_monster";
	inherit "/players/test/file";

	reset(arg)
	{
	  simple_monster::reset(arg);
	  etc.
	which will call reset(arg) in /std/simple_monster.


NOTE
	Although it isn't necessary to start the file name of the inherit file
	with a '/', it does not hurt to do so; in this manner include and
	inherit statements look the same, and you will make fewer mistakes.
