vm-setup contains install scripts designed to start from a clean
Ubuntu image (see comments inside script for which Ubuntu distro) and
install all the courseware needed for the class.
Version numbers in the VM names track the earliest version of the book with which that VM image is designed to work; using that VM with earlier-numbered versions of the book may not give the results the book describes.
appspot contains an AppEngine app deployed to saasbook.appspot.com.
Google graciously donates hosting for the VM image on a high-replication
AppEngine instance. The app's README explains how to administer it and
upload new images there.
Added a new setup script for Ubuntu 12.04 and updated skeletons in new folder hw-skeletons. Details in those folders. - Michael Smith
