+ Notes about the liboil version:
+
+ This program is an adaptation of the Mersenne Twister example
+ program downloaded from the web site listed below. The kernel
+ of the generator is implemented in liboil, and the function
+ genrand_int32() has been replaced with a library call. Note
+ that the liboil function calculates an entire output array at
+ once instead of individually like the original. This makes it
+ easier to use memcpy to copy out many outputs at once.
+
+ Notes from the original authors:
+
+ Any feedback is very welcome.
