/*
 * The assert macro puts diagnostics into programs. When it is executed,
 * if its argument expression is false, it writes information about the
 * call that failed (including the text of the argument, the name of the
 * source file, and the source line number - the latter are respectively
 * the values of the preprocessing macros __FILE__ and __LINE__) on the
 * standard error stream. It then calls the abort function.
 * If its argument expression is true, the assert macro returns no value.
 */

/*
 * Note that <assert.h> may be included more that once in a program with
 * different setting of NDEBUG. Hence the slightly unusual first-time
 * only flag.
