While in the top directory, you will type the following command onto the command line and hit return:
make -f make159 csci159/lab4
This makefile will create a new directory csci159 with a subdirectory
called lab4, and it will populate that directory with some
files that your instructor has provided.
cd into that lab4 directory. Do an "ls".
You are provided with a README. Read the README.
You are also provided, in directory lab4, with
files called makefile, and some data files that end in 'in' or 'inx'.
cat these files; you
can see that they have some data ready to be read in and sorted.
