bytecode version of @command{ocamlc} and @command{ocamllex} that are used to
build the next version of the compiler.  Camlboot implements a bootstrap for
the OCaml compiler and provides a bootstrapped equivalent to these files.

It contains a compiler for a small subset of OCaml written in Guile Scheme,
an interpreter for OCaml written in that subset and a manually-written lexer
for OCaml.  These elements eliminate the need for the binary bootstrap in
OCaml and can effectively bootstrap OCaml 4.07.

This package produces a native @command{ocamlc} and a bytecode @command{ocamllex}.")

@itemize
@item Stream: imperative streams, with in-place update and memoization of
the latest element produced.
@item Genlex: a small parameterized lexical analyzer producing streams of
tokens from streams of characters.
@end itemize

The two modules are designed for use with Camlp4 and Camlp5: The stream
patterns and stream expressions of Camlp4/Camlp5 consume and produce data of
type 'a Stream.t.  The Genlex tokenizer can be used as a simple lexical
analyzer for Camlp4/Camlp5-generated parsers.

The Stream module can also be used by hand-written recursive-descent parsers,
but is not very convenient for this purpose.

The Stream and Genlex modules have been part of the OCaml standard library for a
long time, and have been distributed as part of the core OCaml system.  They
will be removed from the OCaml standard library at some future point, but will
be maintained and distributed separately in the camlpstreams package.")

stores a package, to query metainformation about a package, and to retrieve

allows the user to enter queries on the command-line.  In order to simplify

theory.  The λΠ-calculus is an extension of the simply typed λ-calculus with
dependent types.  The λΠ-calculus modulo theory is itself an extension of the
λΠ-calculus where the context contains variable declaration as well as rewrite

developed in other systems.  In particular, it enjoys a minimalistic syntax.")

@item
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
located errors at little cost
@item
the Concrete Syntax Tree parsers, produce values of type
@code{Parsexp.Cst.t} which record the concrete layout of the s-expression
syntax, including comments

@itemize
@item provide missing features of Unix.create_process such as providing a
working directory,
@item provide better errors when a system call fails in the
sub-process.  For instance if a command is not found, you get a proper
@code{Unix.Unix_error} exception,
@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.")

The pre-processor mode allows mixing documentation and code,

The test mode ensures 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
