 As you are writing your applet, please be aware of the body of pre-existing
-useful functions in utility.c. Use these instead of reinventing the wheel.

-If you use functions from utility.c, you may need to add to the preprocessor
-conditionals in that file, to make sure the routines you need are included.
-So, since your mu implementation used safe_read(), append "|| defined BB_MU" to
-the #if instruction that precedes the safe_read() function in utility.c .

 Additionally, if you have any useful, general-purpose functions in your
 program that could be useful in another program, consider putting them in

 If your program supports flags, the flags should be mentioned on the first

-BB_FEATURE_TRIVIAL_HELP section, one flag per line. (Numerous examples of this
-currently exist in usage.c.)
