+ find directory
+
+This command lists out all files and directories, recursively,
+starting at C<directory>.  It is essentially equivalent to
+running the shell command C<find directory -print> but some
+post-processing happens on the output, described below.
+
+This returns a list of strings I<without any prefix>.  Thus
+if the directory structure was:
+
+ /tmp/a
+ /tmp/b
+ /tmp/c/d

+If C<directory> is not a directory, then this command returns
+an error.

+The returned list is sorted.
