libeasy-format-ocaml-dev 1.2.0-1build2 (i386 binary) in ubuntu focal

 This module offers a simplified interface to the Format module of the
 OCaml standard library. Input data must be converted into a tree
 using 3 kinds of nodes: atoms, lists and labelled nodes. Each node is
 bound to its own formatting parameters and a single function call
 produces the formatted output.
 .
 This package contains the development files for programming with the
 library.
