OCaml Batteries included, or simply "Batteries", is a community-driven
effort to standardize on a consistent, documented, and comprehensive
development platform for the OCaml programming language.

Batteries is meant to serve the following purposes:
- define a standard set of libraries which may be expected on every
compliant installation of OCaml;
- organize these libraries into a hierarchy of modules, with a single
source of documentation;
- define a standard set of language extensions (based on CamlP4) which may
be expected on every compliant installation of OCaml;
- provides a consistent API for otherwise independent libraries.
