Sample free software I write

dockertk — additional tools for docker, and prominently a flexible garbage collector for docker images.

Rashell — a resilient, replicant, shell programming library for OCaml. This library provides primitives to start external processes and gather their output. It differs from many similar facilities in the way it easily manage errors, using monads for operations.

bsdowl — A collection of BSD Make directives aiming at being a universal build system.

Lemonade — A monad library for OCaml, including a PPX rewriter. A sibling project provides monadic stream interface to sqlite.

gasoline — An applicative framework for OCaml.

blueprint — A METAPOST library for blueprints, useful to project maangers and system designers.

cadet — An alternative TeX format, typesetting my documents since 2000.
