%description
Skip is a general-purpose programming language that tracks side effects to
provide caching with reactive invalidation, ergonomic and safe parallelism,
and efficient garbage collection. Skip is statically typed and ahead-of-time
compiled using LLVM to produce highly optimized executables.
