Preserve window layout in Emacs

Question

I have setup my windows in a certain way. How do I save this setting to be invoked later?

Answer 1

I know you allready accepted an answer, however because I understand your question in another way (concerning layout) and this question showed up for me when I was in search for something to persist my emacs window layout, I would like to mention:

workgroups.el

which purpose is to save and restore the way, emacs windows are layed out and many more.
