ocaml-batteries-included 2.10.0-1build2 (s390x binary) in ubuntu focal

 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 metapackage is provided for convenience, to install all of
 batteries included at once.
