+ * has many additional features and is preferable if you can use C++ in
+ * your project.
+ *
+ * Much of the derivation was performed mechanically. In particular, the
+ * output functions were generated by compiling the C++ output functions
+ * into LLVM bitcode and then transforming that using the LLVM C backend
+ * (from https://github.com/draperlaboratory/llvm-cbe), and then
+ * postprocessing and hand editing the output.
+ *
+ * Much of the remaining code was generated by C-preprocessor metaprogramming.

+/* Now, finally we create each of the individual generators. We provide

+ * Implementation notes for boundedrand_r:
+ *
+ * To avoid bias, we need to make the range of the RNG a multiple of
+ * bound, which we do by dropping output less than a threshold.
+ * Let's consider a 32-bit case... A naive scheme to calculate the

+ *
+ * uint32_t threshold = 0x100000000ull % bound;

+ *
+ * uint32_t threshold = (0x100000000ull-bound) % bound;
+ *
+ * because this version will calculate the same modulus, but the LHS
+ * value is less than 2^32.
+ *
+ * (Note that using modulo is only wise for good RNGs, poorer RNGs
