-/* */
-/* Oct - 11 - 2001 Modified */
-/* - fixed a bug in the makefiles, the last make-*/
-/* file was expecting subdirectories. Added */
-/* code to generate a different makefile for */
-/* the last subdirectory. */
-/* - Added logic to first compile all the c files*/
-/* and upon completion remove them. */
-/* - Added multithreading, arguments handling. */
-/* By default the program will generate 8 */
-/* threads, each creating by default 100 deep */
-/* directory tree each containing default 100 */
-/* ".c" files and one makefile. */
-/* - Added usage message. */

-/* - Added logic to print debug messages. */
-/* */
-/* Oct - 16 - 2001 Modified */
-/* - Added sync() calls to commit changes. */
-/* - Fixed bug. pthread_join() returns 0 when */

-/* */
-/* Oct - 20 - 2001 Modified */

-/* - on supplying the full pathname to unlink() */
