+ * Arguments: @const mp *m@ = source
+ * @void *pv@ = pointer to output array
+ * @size_t sz@ = size of the output array
+ *
+ * Returns: ---
+ *
+ * Use: Stores a multiprecision number in an array of octets. The
+ * first byte in the array is the least significant. If the
+ * array is too small to represent the number, high-order bits
+ * are truncated; if the array is too large, high order bytes
+ * are filled with zeros. More formally, if the number is
+ * %$N = \sum{0 \le i} b_i 2^{8i}$% where %$0 \le b_i < 256$%,
+ * then the array is %$b_0, b_1, \ldots, b_{n-1}$%.
