libparsexp-ocaml 0.16.0-3build1 (amd64 binary) in ubuntu noble

 This library provides generic parsers for parsing S-expressions from
 strings or other medium.
 .
 The library is focused on performances but still provide full generic
 parsers that can be used with strings, bigstrings, lexing buffers,
 character streams or any other sources effortlessly.
 .
 It provides three different class of parsers:
  * the normal parsers, producing [Sexp.t] or [Sexp.t list] values;
  * the parsers with positions, building compact position sequences so
    that one can recover original positions in order to report
    properly located errors at little cost;
  * the Concrete Syntax Tree parsers, produce values of type
    [Parsexp.Cst.t] which record the concrete layout of the
    s-expression syntax, including comments.
 .
 This library is portable and doesn't provide IO functions. To read
 s-expressions from files or other external sources, you should use
 parsexp_io.
 .
 This package contains runtime files.
