It is used to save the current directory. Not generally very useful,
unless you don't currently know what directory your in. So, use `pushd'
to push the current directory onto the stack, and use `popd' to `cd' back
to the directory you pushed.
You can also use "cd -" to perform the same thing, except you don't need
the pushd part.
