Organization
-Much of the appendices are integrated into Part II (which enlarges the
-book somewhat). We believe this makes for easier reading. This way, you
-don't have to keep referencing an appendix while you read Part II. That's
-a real chore, especially if you're reading the txt version of this book.
-This book is divided into the following parts:
+This book is divided into the following four parts:
-&pf-oz-organpart1;
-&pf-oz-organpart2;
-&pf-oz-organpart3;
+
+Part I - Introduction
+
+Part I explains a few important things on how to proceed with the
+installation, and gives meta information about the book (version, changelog,
+acknowledgments, associated mailing lists, and so on).
+
+
+
+Part II - Preparing for the build
+
+Part II describes how to prepare for the building process: making a
+partition, downloading the packages, and compiling temporary tools.
+
+
+
+Part III - Building the LFS system
+
+Part III guides you through the building of the LFS system: compiling
+and installing all the packages one by one, setting up the boot scripts, and
+installing the kernel. The resulting basic Linux system is the foundation
+upon which you can build other software, to extend your system in the way
+you like.
+
+
+
+Part IV - Appendix
+
+Part IV for the moment consists of just a single appendix: an alphabetical
+list of all the packages installed, for each package giving its official download
+location, its contents, and its installation dependencies.
+
+(Much of this Appendix A is integrated into Parts II and III. This
+enlarges the book somewhat, but we believe it makes for easier reading. Now
+you don't have to keep referencing the appendix while doing the installation.
+This going back and forth would be a real chore, especially if you're reading
+the txt version of the book.)

-Part II - Installation of the base LFS system

-Part II guides you through the building and installation of an LFS
-system. The resulting LFS system will be the core foundation upon which
-the rest of your Linux system is built. Whatever your system becomes,
-it will be built and supported by the foundation that we build in Part
