Batteries included is a community-driven effort to standardize on an uniform, documented, and comprehensive OCaml development platform. . Batteries included serves 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 one source of documentation * define a standard set of language extensions which may be expected on every compliant installation of OCaml * provide a consistent API for otherwise independent libraries. . This package contains the core part of batteries included: libraries and language extensions for the OCaml language. Using this package you can develop OCaml programs built on top of batteries included.
