+The Source Builder
+------------------
+
+The Source Builder provides a few generic build sets and the configuration
+support to build a number of packages. A project that uses the Source Builder
+can create a specialised set of configuration files that provides the specific
+configurations thet project uses.
+
+For example the RTEMS project provides its own set of configuration files. In
+the build set list in the 'Quick Start' section you can see a build set
++rtems-tools-4.10+. This build set defines the extact configration to use for
+the RTEMS 4.10 release.
