 * Hello World 
 * Read a file containing an arbitrary number of integers, one per line. Display the count, total, and average on stderr at the end of the run. Make the program capable of displaying the maximum values of each quantity without resorting to arbitrary precision arithmetic (hint, unsigned long int). 
 * Use a function/method as part of your program, e.g. to write the aggregated values to stdout. 
-* Use command line parameters available via argv and argc to support -i input-file-name to pass the input file to your program. 
+* Use command line parameters available via argv and argc to support `java my_program input-file-name` to pass the input file to your program.
