+@chapter Development Tools
+
+When porting RTEMS to a new CPU architecture, one will have to have a
+development environment including compiler, assembler, linker, and
+debugger.  The GNU development tool suite used by RTEMS supports most
+modern CPU families.  Often all that is required is to add RTEMS
+configurations for the target CPU family.  RTEMS targets for the GNU tools
+usually start life as little more than aliases for existing embedded
+configurations.  At this point in time, ELF is supported on most of the
+CPU families with a tool target of the form CPU-elf.  If this target is
+not supported by all of the GNU tools, then it will be necessary to
+determine the configuration that makes the best starting point regardless
+of the target object format.
+
+Porting and retargetting the GNU tools is beyond the scope of this manual.  
+The best advice that can be offered is to look at the existing RTEMS
+targets in the tool source and use that as a guideline.
