+mt19937ar.c the C source (ar: initialize by ARray)
+mt19937ar.h the C header file for mt19937ar
+mtTest.c the C test main program of mt19937ar.c
+mt19937ar.out Test outputs of six types generators. 1000 for each
+
+1. Initialization
+ The initialization scheme for the previous versions of MT
+(e.g. 1999/10/28 version or earlier) has a tiny problem, that
+the most significant bits of the seed is not well reflected
+to the state vector of MT.
+
+This version (2002/1/26) has two initialization schemes:
+init_genrand(seed) and init_by_array(init_key, key_length).
+
+init_genrand(seed) initializes the state vector by using
+one unsigned 32-bit integer "seed", which may be zero.
+
+init_by_array(init_key, key_length) initializes the state vector
+by using an array init_key[] of unsigned 32-bit integers
+of length key_kength. If key_length is smaller than 624,
+then each array of 32-bit integers gives distinct initial
+state vector. This is useful if you want a larger seed space
+than 32-bit word.
+
+2. Generation
+After initialization, the following type of pseudorandom numbers
+are available.
+
+genrand_int32() generates unsigned 32-bit integers.
+genrand_int31() generates unsigned 31-bit integers.
+genrand_real1() generates uniform real in [0,1] (32-bit resolution).
+genrand_real2() generates uniform real in [0,1) (32-bit resolution).
+genrand_real3() generates uniform real in (0,1) (32-bit resolution).
+genrand_res53() generates uniform real in [0,1) with 53-bit resolution.
+
+Note: the last five functions call the first one.
+if you need more speed for these five functions, you may
+suppress the function call by copying genrand_int32() and
+replacing the last return(), following to these five functions.
+
+3. main()
+main() is an example to initialize with an array of length 4,
+then 1000 outputs of unsigned 32-bit integers,
+then 1000 outputs of real [0,1) numbers.
+
+4. The outputs
+The output of the mt19937ar.c is in the file mt19937ar.out.
+If you revise or translate the code, check the output
+by using this file.
+
+5. Cryptography
+This generator is not cryptoraphically secure.
+You need to use a one-way (or hash) function to obtain
+a secure random sequence.
