+To run the maze macros with Vim:
+
+	vim -u maze_mac maze_5.78
+	press "g"
+
+The "-u maze.mac" loads the maze macros and skips loading your .vimrc, which
+may contain settings and mappings that get in the way.
+
+
+The original README:
+
+To prove that you can do anything in vi, I wrote a couple of macros that
+allows vi to solve mazes. It will solve any maze produced by maze.c
+that was posted to the net recently.
+
+Just follow this recipe and SEE FOR YOURSELF.
+	1. run uudecode on the file "maze.vi.macros.uu" to
+		produce the file "maze.vi.macros"
+	(If you can't wait to see the action, jump to step 4)
+	2. compile maze.c with "cc -o maze maze.c"
+	3. run maze > maze.out and input a small number (for example 10 if
+		you are on a fast machine, 3-5 if slow) which
+		is the size of the maze to produce
+	4. edit the maze (vi maze.out)
+	5. include the macros with the vi command:
+		:so maze.vi.macros
+	6. type the letter "g" (for "go") and watch vi solve the maze
+	7. when vi solves the maze, you will see why it lies
+	8. now look at maze.vi.macros and all will be revealed
+
+Tested on a sparc, a sun and a pyramid (although maze.c will not compile
+on the pyramid).
+
+Anyone who can't get the maze.c file to compile, get a new compiler,
+try maze.ansi.c which was also posted to the net.
+If you can get it to compile but the maze comes out looking like a fence
+and not a maze and you are using SysV or DOS replace the "27" on the
+last line of maze.c by "11"
+Thanks to John Tromp (tromp@piring.cwi.nl) for maze.c.
+Thanks to antonyc@nntp-server.caltech.edu (Bill T. Cat) for maze.ansi.c.
+
+Any donations should be in unmarked small denomination bills :^)=.
