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.

Where did SCons come from?

SCons began life as the ScCons build tool design which won the Software Carpentry SC Build competition in August 2000. That design was in turn based on the Cons software construction utility. This project has been renamed SCons to reflect that it is no longer directly connected with Software Carpentry (well, that, and to make it slightly easier to type...).
