Co-maintainer of SCons. In my day job, chief scientist and VP of engineering at GenArts.
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.
I'm the co-maintainer of SCons, and one of the original contributors for the past 15 years or so.
