This is a shadow that gets attached to "normal" (ie, fixed) rooms that
used in a region controlled by a topography handler.  It masks
query_dest_other() so that exits from the room get handled correctly.
It also adds certain other functions used by the topography system.
This allows a fixed room to be converted for use in a topography with
minimal changes.<p><b>See also:</b><br>topography

.<ul><a name="add_topo_barriers">
add_topo_barriers</a><pre>
void add_topo_barriers(mapping m)
</pre></br>
This method adds directions from which the room cannot be reached.
The parameter is a mapping, giving the direction as the key and a
message to be printed upon failure as the value.<p>
NOTE: the direction is the direction the person is going (ie, the
command given); e.g., to block access from the west, use "east" as the
key.
<br/><ul>
<li><b>Parameters:</b>
<br/>m - a mapping representing the direction(s) from which to block
access (the key) and a message to be printed (the value).

add_topo_exits</a><pre>
void add_topo_exits(string * other_exits,
                    string other_types)
</pre></br>
This method adds exits for the room if they don't already exist.
"compass4" and "compass8" can be specified as exit names to add
exits for all of the normal 4 or 8 compass directions, respectively.
<br/><ul>
<li><b>Parameters:</b>
<br/>e - array of exit names
<br/>type - type of exit ("path", "road", etc)

</dl>

<ul><a name="query_dest_other">
query_dest_other</a><pre>
varargs mixed * query_dest_other(string direc)
</pre></br>
This method masks the standard query_dest_other() function.  It calls
the topology handler to find the connecting room (which is usually
cloned on-the-fly).
<br/><ul>
<li><b>Parameters:</b>
<br/>direc - room exit name
<li><b>Returns:</b>
<br/>structure describing the exit
<li><b>See also:</b>
<br/>/std/room
.c</dl>

<ul><a name="query_fixed_room">
query_fixed_room</a><pre>
int query_fixed_room()
</pre></br>
This method can be used to determine if this is a fixed room.
<br/><ul>
<li><b>Returns:</b>
<br/>1

</dl>

<ul><a name="query_topo_barrier">
query_topo_barrier</a><pre>
mixed query_topo_barrier(string direc)
</pre></br>
This method returns the message associated with the given barred
direction.
<br/><ul>
<li><b>Parameters:</b>
<br/>direc - the direction to be queried
<li><b>Returns:</b>
<br/>the failure message associated with the given direction
<li><b>See also:</b>

<ul><a name="query_topo_barriers">
query_topo_barriers</a><pre>
mapping query_topo_barriers()
</pre></br>
This method returns the current mapping of barriers.
<br/><ul>
<li><b>Returns:</b>
<br/>the current mapping of barred directions and messages.
<li><b>See also:</b>

<ul><a name="query_topo_handler">
query_topo_handler</a><pre>
string query_topo_handler()
</pre></br>
This method returns the topography handler set for this fixed room.
<br/><ul>
<li><b>Returns:</b>
<br/>the topography handler

This method is deprecated.  Use set_topo_handler().


<ul><a name="set_topo_handler">
set_topo_handler</a><pre>
void set_topo_handler(string s)
