+Directory
+=========
+
+Sets directory options and defines directory aliases.
+
+Options
+-------
+
+  - `AUTO_CD` auto changes to a directory without typing `cd`.
+  - `AUTO_PUSHD` pushes the old directory onto the stack on `cd`.
+  - `PUSHD_IGNORE_DUPS` does not store duplicates in the stack.
+  - `PUSHD_SILENT` does not print the directory stack after `pushd` or `popd`.
+  - `PUSHD_TO_HOME` pushes to the home directory when no argument is given.
+  - `CDABLE_VARS` changes directory to a path stored in a variable.
+  - `AUTO_NAME_DIRS` auto adds variable-stored paths to `~` list.
+  - `MULTIOS` writes to multiple descriptors.
+  - `EXTENDED_GLOB` uses extended globbing syntax.
+  - `CLOBBER` does not overwrite existing files with `>` and `>>`. Use `>!` and
+    `>>!` to bypass.
+
+Aliases
+-------
+
+  - `d` prints the contents of the directory stack.
+  - `1 ... 9` changes the directory to the **n** previous one.
