s.description = <<-DESC.strip_heredoc
**llbuild** is a set of libraries for building build systems. Unlike most build
system projects which focus on the syntax for describing the build, llbuild is
designed around a reusable, flexible, and scalable general purpose *build
engine* capable of solving many "build system"-like problems. The project also
includes additional libraries on top of that engine which provide support for
constructing *bespoke* build systems (like `swift build`) or for building from
Ninja manifests.
