main.c is largely based on
crushes.c in XSadd (https://github.com/MersenneTwister-Lab/XSadd); thus it inherits the MIT License.
PHP Random Function Implementations
This product includes PHP, freely available from http://www.php.net/. Specifically, files
rand_php_mt_fixed.c are generally extraction from the original PHP implementation (https://github.com/php/php-src); thus they inherit the PHP license.
