+// A library of seedable RNGs implemented in Javascript.
+//
+// Usage:
+//
+// var seedrandom = require('seedrandom');
+// var random = seedrandom(1); // or any seed.
+// var x = random();       // 0 <= x < 1.  Every bit is random.
+// var x = random.quick(); // 0 <= x < 1.  32 bits of randomness.
+
+// alea, a 53-bit multiply-with-carry generator by Johannes Baagøe.
+// Period: ~2^116
+// Reported to pass all BigCrush tests.
+var alea = require('./lib/alea');
+
+// xor128, a pure xor-shift generator by George Marsaglia.
+// Period: 2^128-1.
+// Reported to fail: MatrixRank and LinearComp.
+var xor128 = require('./lib/xor128');
+
+// xorwow, George Marsaglia's 160-bit xor-shift combined plus weyl.
+// Period: 2^192-2^32
+// Reported to fail: CollisionOver, SimpPoker, and LinearComp.
+var xorwow = require('./lib/xorwow');
+
+// xorshift7, by François Panneton and Pierre L'ecuyer, takes
+// a different approach: it adds robustness by allowing more shifts
+// than Marsaglia's original three.  It is a 7-shift generator
+// with 256 bits, that passes BigCrush with no systmatic failures.
+// Period 2^256-1.
+// No systematic BigCrush failures reported.
+var xorshift7 = require('./lib/xorshift7');
+
+// xor4096, by Richard Brent, is a 4096-bit xor-shift with a
+// very long period that also adds a Weyl generator. It also passes
+// BigCrush with no systematic failures.  Its long period may
+// be useful if you have many generators and need to avoid
+// collisions.
+// Period: 2^4128-2^32.
+// No systematic BigCrush failures reported.

+// number generator derived from ChaCha, a modern stream cipher.

+// Period: ~2^127
+// No systematic BigCrush failures reported.
