HOW WE ACCIDENTALLY BUILT A BETTER BUILD SYSTEM FOR OCAML

Summary from the TLDR Web Dev newsletter

Jane Street initially created Jenga, an OCaml build system, but its limited reach and platform incompatibility led to its un-open-sourcing. It then developed Jbuilder, a simpler, cross-platform tool, which unexpectedly gained popularity due to its speed. Jbuilder evolved into Dune, a more robust build system, after a name change and significant community contributions.
