+Answer the following questions to describe your code submission. Please keep
+all lines to a maximum of 80 characters wide.
+
+1 - When implementing the built-ins, which ones essentially only required
+    making a call to an existing C function? What function(s)?
+
+    The pwd, cd, and quit are essentially just calls to c functions. 
+
+2 - Briefly describe how you sorted the files in the ls program. If you used
+    an existing C function to sort, explain the arguments you passed.
+
+    We created a custom, leading dot ignoring, case-insensitive comparison
+    function that can be used by scandir to sort the files before they are
+    returned to us. The two arguments we two dirents, the names of which
+    were compared, and an integer returned to tell scandir which should be
+    sorted first.
+
+3 - If you used your lab 2 code to parse the command line, briefly describe
+    any changes or adaptations you made. If you didn't use lab 2, briefly
+    describe how you built the array of arguments to pass when executing the
+    program.
+
+    Most of the code from lab 2 was fairly plug in play. The only adaptation 
+    necessary was turning the parse_buffer and functions process.c to use the 
+    fsm from lab2 instead of just strings.
