TeX by Topic

This book treats the various aspects of TeX in chapters that are concerned with relatively small, well-delineated, topics. In this chapter, therefore, a global picture of the way TeX operates will be given. Of necessity, many details will be omitted here, but all of these are treated in later chapters. On the other hand, the few examples given in this chapter will be repeated in the appropriate places later on; they are included here to make this chapter self-contained.
