-This is useful if you want to peruse and move around in an ls -lR

+ "Try to make the current buffer into a Dired buffer.
+This command is rarely useful, but may be convenient if you want
+to peruse and move around in the output you got from \"ls
+-lR\" (or something similar), without having access to the actual
+file system.
+
+Most Dired commands that don't consult the file system will work
+as advertised, but commands that try to alter the file system
+will usually fail. (If the output is from the current system,
+most of those commands, too, will work fine.)
If you have saved a Dired buffer in a file you can use \\[dired-virtual] to
resume it in a later session.
