-The language may be either C or Ada and there is
-currently nothing shared between the source trees for these two
-implementations of RTEMS.  The user generally selects the
-subdirectory for the implementation they are using and ignores
-that for the other implementation.  The only exceptions to this
-normally occurs when comparing the source code for the two
-implementations or when porting both to a new CPU or target
-board.  The following shows the top level RTEMS directory
-structure which includes directories for each language
-implementation and a language independent source documentation
-directory.  The source documentation directory is currently not
-supported.
+Each of the following sections will describe the

+@item $@{RTEMS_ROOT@}/aclocal/
+This directory contains the custom M4 macros which are available to
+the various GNU autoconf @code{configure.ac} scripts throughout 
+the RTEMS source tree.  GNU autoconf interprets @code{configure.ac}
+files to produce the @code{configure} files used to tailor 
+RTEMS build for a particular host and target environment.  The
+contents of this directory will not be discussed further in this
+document.
+
+@item $@{RTEMS_ROOT@}/automake/
+This directory contains the custom GNU automake fragments 
+which are used to support the various @code{Makefile.am}
+files throughout the RTEMS source tree.  The
+contents of this directory will not be discussed
+further in this document.
+
+@item $@{RTEMS_ROOT@}/c/
+This directory is the root of the portions of the RTEMS source
+tree which must be built tailored for a particular CPU model
+or BSP.  The contents of this directory will be discussed
+in the @ref{Directory Structure c/ Directory} section.
+
+@item $@{RTEMS_ROOT@}/contrib/
+This directory contains contributed support software.  Currently
+this directory contains the RPM specifications for cross-compilers
+hosted on GNU/Linux that target Cygwin and Solaris.  The 
+cross-compilers produced using these specifications are then
+used in a Canadian cross build procedure to produce the Cygwin
+and Solaris hosted RTEMS toolsets on a GNU/Linux host.  This
+directory will not be discussed further in this document.
+
+@item $@{RTEMS_ROOT@}/cpukit/
+This directory is the root for all of the "multilib'able"
+portions of RTEMS.  This is a GNU way of saying the the
+contents of this directory can be compiled like the 
+C Library (@code{libc.a}) and the functionality is 
+neither CPU model nor BSP specific.  The source code
+for most RTEMS services reside under this directory.
+The contents of this directory will be discussed
+in the @ref{Directory Structure CPUKit Directory} section.
+
+@item $@{RTEMS_ROOT@}/doc/
+This directory is the root for all RTEMS documentation.
+The source for RTEMS is written in GNU TeXinfo and 
+used to produce HTML, PDF, and "info" files.
+The RTEMS documentation is configured, built,
+and installed separately from the RTEMS executive and tests.
+The contents of this directory will be discussed
+in the @ref{Directory Structure Documentation Directory} section.
+
+@item $@{RTEMS_ROOT@}/make/
+This directory contains files which support the
+RTEMS Makefile's.  From a user's perspective, the
+most important parts are found in the @code{custom/}
+subdirectory.  Each ".cfg" file in this directory
+is associated with a specific BSP and describes
+the CPU model, compiler flags, and procedure to
+a produce an executable for the target board.
+These files are described in detail in the
+@b{RTEMS BSP and Device Driver Development Guide}
+and will not be discussed further in this document.
+
+@item $@{RTEMS_ROOT@}/scripts/
+This directory contains the RPM specifications for the
+prebuilt cross-compilation toolsets provided by the
+RTEMS project.  There are separate subdirectories
+for each of the components in the RTEMS Cross Compilation
+Environment including @code{binutils/}, @code{gcc3newlib/},
+and @code{gdb/}.  This directory is configured, built,
+and installed separately from the RTEMS executive
+and tests.  This directory will not be discussed further
+in this document.
+
+@item $@{RTEMS_ROOT@}/tools/
+This directory contains RTEMS specific support utilities which
+execute on the development host.  These utilities are divided
+into subdirectories based upon whether they are used in the process
+of building RTEMS and applications, are CPU specific, or are
+used to assist in updating the RTEMS source tree and applications. 
+The support utilities used in the process of building RTEMS are
+described in @ref{RTEMS Specific Utilities}.  These are the
+only components of this subtree that will be discussed in this
+document.

-The top level directory structure for the C implementation of RTEMS 
-is as follows:
+@table @code
+@item $@{RTEMS_ROOT@}/c/src/ada-tests/
+This directory contains the test suite for the Ada
+language bindings to the Classic API.
+
+@item $@{RTEMS_ROOT@}/c/src/lib/
+
+@item $@{RTEMS_ROOT@}/c/src/libchip/
+This directory contains device drivers for various
+peripheral chips which are designed to be CPU and
+board dependent.  This directory contains a variety
+of drivers for serial devices, network interface
+controllers, and real-time clocks.
+
+@item $@{RTEMS_ROOT@}/c/src/libmisc/
+This directory contains support facilities which 
+are RTEMS specific but otherwise unclassified.  In
+general, they do not adhere to a standard API.  
+Among the support facilities in this directory are
+a @code{/dev/null} device driver, the Stack
+Overflow Checker, a mini-shell, the CPU and 
+rate monotonic period usage monitoring libraries,
+and a utility to "dump a buffer" in a nicely
+formatted way similar to many ROM monitors.
+
+@item $@{RTEMS_ROOT@}/c/src/libnetworking/
+This directory contains the networking components which
+might be tailored based upon the particular BSP.  This
+includes the RTEMS telnetd, httpd, and ftpd servers.
+
+@item $@{RTEMS_ROOT@}/c/src/librdbg/
+This directory contains the Ethernet-based remote debugging
+stub.  This software must be built to be intimately aware
+of a particular CPU model.
