+ This section will describe all of the different + types of files that you can build with &SCons;, + and the built-in &Builder; objects used to build them. + By default, all of the &Builder; objects in this section + can be built either with or without an explicit + construction environment. + + </para> + + <section> + <title>Programs: the &Program;
