@section Generate RTEMS for a Specific Target and BSP
+@subsection Using the bit_rtems script
+The simplest way to build RTEMS is to use the @code{bit_rtems} script.
+This script interprets the settings in the @code{user.cfg} file to
+enable or disable the various RTEMS options.
+This script is invoked as follows:
+./bit_rtems CPU [BSP]
+@end example
+Where CPU is one of the RTEMS supported CPU families from the following

+@item hppa1.1
+@item i386

+BSP is a supported BSP for the selected CPU family. The list of
+supported BSPs may be found in the file
+in the RTEMS source tree. If the BSP parameter is not specified,
+then all supported BSPs for the selected CPU family will be built.
+@b{NOTE:} The POSIX API must be enabled to use GNAT/RTEMS.
+@subsection Using the RTEMS configure Script Directly
Make a build directory under tools and build the RTEMS product in this
directory. The ../@value{RTEMS-UNTAR}/configure
command has numerous command line
arguments. These arguments are discussed in detail in documentation that
comes with the RTEMS distribution. In the installation described in the
section "Unpack the RTEMS source", these configuration options can be found
-in file tools/@value{RTEMS-UNTAR}/README.configure.

The GNAT/RTEMS run-time implementation is based on the POSIX API. Thus
the RTEMS configuration for a GNAT/RTEMS environment MUST include the
