+ * The fast math code uses an array of a fixed size to store the big integers.
+ * By default, the array is big enough for RSA keys. There is a size,
+ * FP_MAX_BITS which can be used to make the array smaller when one wants ECC
+ * but not RSA. Some people want fast math sized for both RSA and ECC, where
+ * ECC won't use as much as RSA. The flag ALT_ECC_SIZE switches in an alternate
+ * ecc_point structure that uses an alternate fp_int that has a shorter array
+ * of fp_digits.
+ *
+ * Now, without ALT_ECC_SIZE, the ecc_point has three single item arrays of
+ * mp_ints for the components of the point. With ALT_ECC_SIZE, the components
+ * of the point are pointers that are set to each of a three item array of
+ * alt_fp_ints. While an mp_int will have 4096 bits of digit inside the
+ * structure, the alt_fp_int will only have 512 bits for ECC 256-bit and
+ * 1056-bits for ECC 521-bit. A size value was added in the ALT case, as well,
+ * and is set by mp_init() and alt_fp_init(). The functions fp_zero() and
+ * fp_copy() use the size parameter. An int needs to be initialized before
+ * using it instead of just fp_zeroing it, the init will call zero. The
+ * FP_MAX_BITS_ECC defaults to calculating based on MAX_ECC_BITS, but
+ * can be set to change the number of bits used in the alternate FP_INT.
+ *
+ * The ALT_ECC_SIZE option only applies to stack based fast math USE_FAST_MATH.
