+//@ Available options:

+//@ + `-n`: Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.
+//@
+//@ Arguments:
+//@
+//@ + `dir`: Makes the current working directory be the top of the stack, and then executes the equivalent of `cd dir`.
+//@ + `+N`: Brings the Nth directory (counting from the left of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
+//@ + `-N`: Brings the Nth directory (counting from the right of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
+//@
+//@ Examples:
+//@
+//@ ```javascript
+//@ // process.cwd() === '/usr'
+//@ pushd('/etc'); // Returns /etc /usr
+//@ pushd('+1');   // Returns /usr /etc
+//@ ```
