libfindlib-ocaml binary package in Ubuntu Focal amd64

 The "findlib" OCaml library provides a scheme to manage reusable
 software components (packages), and includes tools that support this
 scheme. Packages are collections of OCaml modules for which
 metainformation can be stored. The packages are kept in the
 filesystem hierarchy, but with strict directory structure. The
 library contains functions to look the directory up that stores a
 package, to query metainformation about a package, and to retrieve
 dependency information about multiple packages.
 .
 This package contains files that are or may be needed at runtime by
 programs using findlib (META files and dynamically-loadable files).
