Stephen Sherratt maintains a focused portfolio of OCaml-centric development tools that streamline the traditionally terse toolchain of the functional language. Alice, branded as a “radical” build system, replaces the venerable Make and Dune patterns with a concise, declarative syntax and aggressive parallelization, cutting compile times for large OCaml codebases while auto-generating lock files that guarantee reproducible builds across Unix, Windows, and continuous-integration containers. Complementing it, opam serves as the de-facto package manager for the OCaml ecosystem, offering a versioned switch model that lets developers hop between compiler releases, experimental flambda variants, or 32-bit cross-compilation targets without trashing the host environment; its dependency solver respects semantic-version constraints and can sandbox untrusted code during compilation, making it equally useful for academic researchers, fintech engineers shipping statically-linked microservices, and teachers who need a friction-free way to supply coursework libraries. Together the pair form a minimal yet complete pipeline: opam fetches and pins packages, Alice orchestrates incremental builds, and the resulting native artifacts can be pushed to Docker registries or embedded in VSCode dev-containers. All utilities are cross-signed binaries that update through GitHub releases and integrate with existing Cygwin or WSL setups on Windows. Stephen Sherratt’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest upstream versions and supporting batch installation of multiple applications.
