> OCaml is an industrial strength programming language supporting functional, imperative and object-oriented styles. It has in recent years seen a marked increase in development activity, particularly in the compiler itself [1], core libraries [2] and developer tools [3]. Many of these newer libraries and features are already dependencies of a number of large upstream projects [4].

I see the OCaml SIG providing the current stable compiler (4.02.1 at time of writing), and a selection of useful libraries and developer tools. This could then be used as a basis for other applications or SIGs to build upon - for example, it would make CentOS a good platform for building Unikernels [5] and it would be helpful in getting the Xapi Project suite of daemons [4] into one of the virtualisation/cloud SIGs. We actually already have a number of specs that are built for CentOS 6 which could make a good starting point [6].

We might be able to do this as part of the current Virt SIG if everyone
there agrees.

I know that we want to use a newer OCaml for xen on both c6 and c7.
