// UnitTests
//
// This is a program to directly test various functions, without going
// through a PSP. Especially useful for things like opcode emitters,
// hashes, and various data conversion utility function.
//
// TODO: Make a test of nice unittest asserts and count successes etc.
// Or just integrate with an existing testing framework.
