NAME
    Oz - Perl interface for executing applications in the Oz programming
    language

  SYNOPSIS
      use Oz;
      
  my $code = <<'END_OZ';
      {Show "Hello World!"}
      END_OZ
      
  # One line idiomatic execution of Oz code.
      # Returns the content of STDOUT after the script.
      my $stdout = Oz::Script->new( \$script )->run;
      
  # The longhand equivalent of the above.
      my $script = Oz::Script->new( \$script );
      my $ozc    = Oz::Compiler->new( script => $script );
      my $output = $ozc->run;
      
  # Generate an executable for the script.
      $ozc->make_exe or die "Failed to create executable";
      print "Created " . $ozc->main_exe . "\n";

DESCRIPTION
    Oz is a Perl wrapper for the Oz programming language and the Mozart Oz
    compiler. It provides a convenient mechanism for taking simple Oz
    scripts, compiling them, executing them, and capturing the resulting
    output.

  About Oz and Mozart
    The Mozart Programming System is an advanced development platform for
    intelligent, distributed applications. The system is the result of a
    decade of research in programming language design and implementation,
    constraint-based inference, distributed computing, and human-computer
    interfaces.

    Mozart is based on the Oz language, which supports declarative
    programming, object-oriented programming, constraint programming, and
    concurrency as part of a coherent whole. For distribution, Mozart
    provides a true network transparent implementation with support for
    network awareness, openness, and fault tolerance. Mozart supports
    multi-core programming with its network transparent distribution and is
    an ideal platform for both general-purpose distributed applications as
    well as for hard problems requiring sophisticated optimization and
    inferencing abilities.

  Why is Oz.pm needed
    In an ideal world, a module wrapper for something as simple as compiling
    a basic program should not really be necesary. Unfortunately, the
    dominent toolchain for Oz (the Mozart Programming System) assumes that
    anyone writing Oz will be using the Emacs editor to do so.

    As a result, most tutorial information for beginners does not cover the
    creation of pure Oz programs, or the compilation of these programs.
    Instead, it assumes the use of an Emacs specific layer over the top of
    the language, and covers the execution of any resulting programs
    exclusively from inside of Emacs.

    Oz is a Perl module which simplifies the tortuous and badly documented
    process of taking pure Oz source code and turning it into an actual
    working program that you can execute using the underlying ozc compiler.

    It is a fairly simple module designed for simple uses of the Oz
    programming language to solve cross-domain programs that would otherwise
    be extremely difficult or slow in Perl (such as logic programming or
    constraint-based programming).

    The two interfaces to the Oz compiler are documented below. For the time
    being the code in the synopsis above should be enough to get you started
    working with these modules. See the source code to Oz::Compiler or
    Oz::Script for the full set of supported methods.

  Oz::Compiler
    The Oz::Compiler module provides an interface directly over the ozc
    compiler that ships with Mozart.

    It provides the basic service for taking Oz scripts in the form of
    Oz::Script objects and generating command line calls to the compiler to
    create executable files, as well as the various intermediate "ozf",
    "ozi", "ozm" forms of the code.

    It also provides the ability to execute the resulting executable in a
    temp directory, returning the output of the program.

  Oz::Script
    The Oz::Script module provides an abstraction for a single Oz script,
    either from a location on disk or from an arbitrary string.

    It contains a convenience "run" method which abstracts away dealings
    with the Oz::Compiler method, so you can take a string of Oz code and
    execute it directly, returning the output of the program.

SUPPORT
    Please note that this module is only a first step at an interface for
    the Oz programming language and was created to solve a specific limited
    problem. It is being provided to CPAN as a courtesy and by no means
    represents a complete work (what function is implemented is however
    solid and stable).

    If you are interested in taking this module beyond the current
    implementation, I would love to hear from you and would be happy to let
    you take it over or have commit to the repository.

    Bugs should be reported via the CPAN bug tracker at

ACKNOWLEDGEMENTS
    A huge thanks to my partner in crime Jeffery Candiloro, who actually had
    the patience to learn the Oz language enough to write real programs when
    I was struggling with it, and who wrote all the real Oz code we executed
    in production with this module.
