-Building Tools and RTEMS
-========================
-
-The Quick Start section of the RTEMS Users Guide covers the typical
-information and process needed to build both an RTEMS toolset and
-RTEMS itself. This section has information on specific configuration
-options that may be needed.
-
-Controlling the Build
----------------------
-
-Build sets can be controlled via the command line to enable and disable various
-features. There is no definitive list of build options that can be listed
-because they are implemented with the configuration scripts. The best way to
-find what is available is to grep the configuration files. for ``with`` and
-``without``.
-
-Following are currently available:
-
-``--without-rtems``
-  Do not build RTEMS when building an RTEMS build set.
-
-``--without-cxx``
-  Do not build a C++ compiler.
-
-``--with-ada``
-  Attempt to build an Ada compiler.  You need a native GNAT installed.
-
-``--with-fortran``
-  Attempt to build a Fortran compiler.
-
-``--with-objc``
-  Attempt to build a C++ compiler.
