From [http://www.scons.org/ the website]:
 SCons is an Open Source software construction tool—that is, a next-generation build tool. Think of SCons as an improved, cross-platform substitute for the classic {{{Make}}} utility with integrated functionality similar to {{{autoconf/automake}}} and compiler caches such as {{{ccache}}}. In short, SCons is an easier, more reliable and faster way to build software.
