## AI overview

Jane Street announces OxCaml, its branch of the OCaml compiler. OxCaml provides open-source language extensions intended to improve OCaml for performance engineering, with a new website offering installation instructions, tutorials, and documentation.

## Source excerpt

At Jane Street, we've been actively making improvements to OCaml for a long time. Over the last few years, we've started to build some fairly ambitious extensions to the language. Our aim is to make OCaml a great language for performance engineering. This work has always been open source, and our hope is to contribute these extensions to upstream OCaml, but we're still iterating on their design as we gain experience using them. As such, we think the time has come to make it easier for people to use our extensions in the outside world. That starts with giving our branch of the compiler the three most important components of a modern programming language: a cool name, a cute logo and a snazzy website. So, without further ado, we are excited to announce OxCaml.
