"As you will see in the next sections of this guide many
different files are required to successfully use Amazon's EC2 Web
Services. For the sake of simplicity we will created directory
"aws" in ~/ and store all necessary files there for a quick access.
There will be three exceptions:
* AWS's api and ami tools which we will install into /opt
directory
* chroot environment will be created in /chroot
* Amazon's account certificate and private key will be stored in
~/.ec2 "
