+Preface
+=======
+
+The purpose of this manual is to provide a roadmap to those people porting
+RTEMS to a new CPU family. This process includes a variety of activities
+including the following:
+
+- targeting the GNU development tools
+
+- porting the RTEMS executive code
+
+- developing a Board Support Package
+
+- writing an RTEMS CPU Supplement manual for the completed port.
+
+This document focuses on the process of actually porting the RTEMS
+executive code proper. Each of the data structures, routines, and macro
+definitions required of a port of RTEMS is described in this document.
+
+Porting any operating system, including RTEMS, requires knowledge of the
+operating system, target CPU architecture, and debug environment. It is
+very desirable to have a CPU simulator or hardware emulator when debugging
+the port. This manual assumes that the user is familiar with building and
+using RTEMS, the C programming language, and the target CPU architecture.
+It is desirable to be familiar with the assembly language for the target
+CPU family but since only a limited amount of assembly is required to port
+RTEMS.
