.B \-dead\-color \fIcolor\fP
The color of the failed path (it is also stippled with a 50% pattern.)
.TP 8
+.B \-skip\-color \fIcolor\fP
+The maze solver will choose to not go down a path if it can "see" (in a
+straight line) that it is a dead end. This is the color to use for paths
+that are skipped for this reason.
+.TP 8
+.B \-surround\-color \fIcolor\fP
+If the maze solver ever completely encloses an area within the maze, then
+it knows that the exit is not in there (and in fact the interior of that
+area might not even be reachable.) It will mark out those cells using this
+color.
+.TP 8
.B \-solve\-delay \fIinteger\fP
Delay (in microseconds) between each step of the solution path.
Default 5000, or about 1/200th second.
