I expected to see a “Developer folder” on the HDD and I’m using Mac OS X Lion 10.7.4 but there is none.

I’ve downloaded ‘Command Line Tools for Xcode’ from ‘Downloads Apple Developers’ with this link
I’ll be using HTML, CSS and Javascript to develop an app through Xcode. I’ve Xcode installed and registered with Apple. Am I missing something?
It appears that they scrapped the /Developer folder, and are now keeping everything inside the /Applications/Xcode.app/…
