==Description==

The extensions mechanism is a general method of attaching functionality
modules to objects. It is specifically intended to replace the (extremely
troublesome) method of adding functionality by multiple inheritance.

Generally, all you need to do in order to use extensions, as a content
developer, is to place a statement like the following in a configure():

add_extension(LS_Extension("post_office"));

This example is how you add post office functionality to a room. The
LS_Extension() macro is from master.h (do #include <master.h>), and should
always be used instead of literal pathnames.

Extensions are supported by anything that inherits /std/item, /std/room,
/std/daemon, or /mod/character/body.

The lib's supply of extension modules is located in /obj/extensions, which
is the directory referred to by the LS_Extension() macro.

In their internals, extensions work in a matter fairly similar to the
affiliation support. More information will be forthcoming at a later date.
The curious are referred to the code; the post office extension is a very
simple, straightforward example.
