elpa-tuareg 1:3.0.1-1 (s390x binary) in ubuntu mantic

 OCaml (Objective Caml) is a programming language featuring functional
 programming, mutable data structures, algebraic data types, and type
 inference.
 .
 This package provides tuareg-mode for editing OCaml programs with
 Emacs and XEmacs. It also works on Caml Light, the predecessor
 language of OCaml.
 .
 Tuareg handles automatic indentation of Objective Caml and Caml-Light
 code. Key parts of the code are highlighted using Font-Lock. It
 provides support to run an interactive OCaml toplevel and debugger.
 .
 Another popular emacs mode for editing OCaml files is caml-mode,
 available through the elpa-caml package. Tuareg attempts to give
 better results than caml-mode. Indentation rules are slightly
 different but closer to classical functional languages
 indentation. Tuareg gives access to some functionalities from
 caml-mode.
