Simply load the zero dependency @code{down} library in the @command{ocaml}
toplevel and you get line edition, history, session support and identifier
completion and documentation with @command{ocp-index}.

Add this to your @file{~/.ocamlinit}:

@example
#use \"down.top\"
@end example

You may also need to add this to your @file{~/.ocamlinit} and declare
the environment variable @code{OCAML_TOPLEVEL_PATH}:

@example
let () =
  try Topdirs.dir_directory (Sys.getenv \"OCAML_TOPLEVEL_PATH\")
  with Not_found -> ()
@end example

OR

@example
let () = String.split_on_char ':' (Sys.getenv \"OCAMLPATH\")
         |> List.filter (fun x -> Filename.check_suffix x \"/site-lib\")
         |> List.map (fun x -> x ^ \"/toplevel\")
         (* remove the line below if you don't want to see the text
            every time you start the toplevel *)
         |> List.map (fun x -> Printf.printf \"adding directory %s\\n\" x; x)
         |> List.iter Topdirs.dir_directory;;
@end example")

packages are kept in the file system 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.  There is also a tool that
allows the user to enter queries on the command-line.  In order to simplify
compilation and linkage, there are new frontends of the various OCaml

the normal parsers, producing [Sexp.t] or [Sexp.t list] values
@item
the parsers with positions, building compact position sequences so
that one can recover original positions in order to report properly

@item
the Concrete Syntax Tree parsers, produce values of type
@code{Parsexp.Cst.t} which record the concrete layout of the s-expression

@item improve performances by using vfork when available.  It is often
claimed that nowadays fork is as fast as vfork, however in practice
fork takes time proportional to the process memory while vfork is
constant time.  In application using a lot of memory, vfork can be
thousands of times faster than fork.

parsers are wrapped in a simple interface: they are functions that transform
byte streams to parsing signal streams.  Streams can be manipulated in various
ways, such as processing by fold, filter, and map, assembly into DOM tree
structures, or serialization back to HTML or XML.

Both parsers are based on their respective standards.  The HTML parser, in
particular, is based on the state machines defined in HTML5.

The parsers are error-recovering by default, and accept fragments.  This makes
it very easy to get a best-effort parse of some input.  The parsers can,
however, be easily configured to be strict, and to accept only full documents.

Apart from this, the parsers are streaming (do not build up a document in
memory), non-blocking (can be used with threading libraries), lazy (do not
consume input unless the signal stream is being read), and process the input in
a single pass.  They automatically detect the character encoding of the input
stream, and convert everything to UTF-8.")

There are (currently) two sub-commands, corresponding
to two modes of operations: pre-processing (@code{ocaml-mdx pp})
and tests (@code{ocaml-mdx test}]).

The pre-processor mode allows to mix documentation and code,
and to practice @dfn{literate programming} using markdown and OCaml.

The test mode allows to ensure that shell scripts and OCaml fragments
in the documentation always stays up-to-date.

@code{ocaml-mdx} is released as two binaries called @code{ocaml-mdx} and
@code{mdx} which are the same, mdx being the deprecated name, kept for now for
compatibility.")
