 ## Lab Assignments
 
-The labs all share some common features. Each lab is distributed in a self-contained tar file. You will need a CS:APP account to download the code. To untar foo.tar, type "`tar xvf foo.tar`" to the Unix shell. This will create a directory called "`foo`" that contains all of the material for the lab.

-Handout directories for each lab (without solutions) are available to students who are using the book for self-study and who want to work on the labs. Solutions are provided only to instructors.
