This book is intended for anyone considering using Open Source. It describes what open source is, discusses business reasons for using open source, and describes how an open source project works in a day-to-day manner. It will help you decide on whether open source is right for your project, and, if so, what steps you should take to proceed and some mistakes you should avoid."
