librss-ocaml-dev 2.2.1-3build16 (armhf binary) in ubuntu focal

 This package is a small OCaml library providing functions to parse and print
 RSS 2.0 files. The parser can also parse some RDF files, but some fields are
 not taken into account. There is still some work to do (add missing RSS 2.0
 attributes, add convenient functions).
 .
 OCaml-RSS was previously part of Cameleon but is now developed separately
 and is findlib compatible.
 .
 This package contains all the development stuff you need to develop
 OCaml programs which use OCaml-RSS.
