10. From the main directory, under lib, make a directory named plri3
Inside the plri3 directory, issue the following command:
mkdir A-E F-J K-O P-T U-Z ZZZ
11. Run your configure script according to the directions that came with Circle.
Return to the main I3.txt file and continue where you left off.
