In this chapter, you were presented with the advantages of open source, and examples of how open source helped the Linux kernel, Yocto Project, OpenEmbedded, and Buildroot for the development and growth of projects, such as LTIB and Scratchbox; the lack of open source contribution meant the deprecation and disappearance of them over time. The information presented to you will be in the form of examples, which will give you a clearer idea of the concepts in this book.

In the next chapter, there will be more information on toolchains and its constituent components. Exercises that give you a better idea of toolchains will be generated using both the manual and automatic approach.
