/**
 * <rc_usefulincludes.h>
 *
 * This may be used as an "uber-include" at the beginning of a c file to include
 * the most common C libs without having a cluttered list. This is technically
 * bad practice and you should include only the headers necessary for your
 * program to operate. However, this can save time while quickly prototyping and
 * remains for backwards compatability.
