I really like open source software. They save time and money, are adaptable, and are simple to use. But what if there isn't an open source tool available for what you require? Over the past year, I've had the opportunity to use this incredible tool. Merlin, I must add, is a magical tool that can do everything from collect data to analyse it intricately to give you what you need, all while making it appear as though magic was used throughout.
