-cdec is a fast decoder.
-
-SPEED COMPARISON
-------------------------------------------------------------------------------
-
-Here is a comparison with a couple of other decoders doing SCFG decoding:
-
-  Decoder  Lang.   BLEU    Run-Time        Memory
-  cdec     c++     31.47   0.37 sec/sent   1.0-1.1GB
-  Joshua   Java    31.55   2.34 sec/sent   4.0-4.8GB
-  Hiero    Python  31.22   27.2 sec/sent   1.7-1.9GB
-
-The maximum number of pops from candidate heap at each node is k=30, no other
-pruning, 3gm LM, Chinese-English translation task.
-
-
-GETTING STARTED
-------------------------------------------------------------------------------
-
-See the BUILDING file for instructions on how to build the software.  To
-explore the decoder's features, the best way to get started is to look
-at cdec's command line options or to have a look at the test cases in
-the tests/system_tests/ directory.  Each of these can be run with a command
-like ./cdec -c cdec.ini -i input.txt -w weights .  The files should be
-self explanatory.
-
-
-EXTRACTING A SYNCHRONOUS GRAMMAR / PHRASE TABLE
-------------------------------------------------------------------------------
-cdec does not include code for generating grammars.  To build these, you will
-need to write your own software or use an existing package like Joshua, Hiero,
-or Moses.
-
-
-OPTIMIZING / TRAINING MODELS
-------------------------------------------------------------------------------
-cdec does include code for optimizing models, according to a number of
-training criteria, including training models as CRFs (with latent derivation
-variables), MERT (over hypergraphs) to opimize BLEU, TER, etc.
-
-Eventually, I will provide documentation for this.
-
-
-ALIGNMENT / SYNCHRONOUS PARSING / CONSTRAINED DECODING
-------------------------------------------------------------------------------
-cdec can be used as an aligner.  For examples, see the test cases.

+`cdec` is a research platform for machine translation and similar structured prediction problems.
+
+## Installation
+
+Build `cdec`:
+
+	autoreconf -ifv
+	./configure
+	make
+	./tests/run-system-tests.pl
+
+You will need the following libraries / tools:
+
+- [Autoconf / Automake / Libtool](http://www.gnu.org/software/autoconf/)
+    - Older versions of GNU autotools may not work properly.
+- [Boost C++ libraries (version 1.44 or later)](http://www.boost.org/)
+    - If you build your own boost, you _must install it_ using `bjam install`.
+    - Older versions of Boost _may_ work, but problems have been reported with command line option parsing on some platforms with older versions.
+- [GNU Flex](http://flex.sourceforge.net/)
+
+## Further information
+
+[For more information, refer to the cdec documentation](http://www.cdec-decoder.org)
+

+This is an example of an _external_ feature function which is loaded as a dynamically linked library at run time to compute feature functions over derivations in a hypergraph. To load feature external feature functions, you can specify them in your `cdec.ini` configuration file as follows:

+
+Any extra options are passed to the external library.
+
+*Note*: the build system uses [GNU Libtool](http://www.gnu.org/software/libtool/) to create the shared library. This may be placed in a hidden directory called `./libs`.

- * This class implements the projected gradiend
- * as described in Bertsekas "Non Linear Programming"
- * section 2.3.
- * 
- * The update is given by:
- * x_k+1 = x_k + alpha^k(xbar_k-x_k)
- * Where xbar is:
- * xbar = [x_k -s_k grad(f(x_k))]+
- * where []+ is the projection into the feasibility set
- * 
- * alpha is the step size 
- * s_k - is a positive scalar which can be view as a step size as well, by 
- * setting alpha to 1, then x_k+1 = [x_k -s_k grad(f(x_k))]+
- * This is called taking a step size along the projection arc (Bertsekas) which
- * we will use by default.
- * 
- * Note that the only place where we actually take a step size is on pick a step size
- * so this is going to be just like a normal gradient descent but use a different 
- * armijo line search where we project after taking a step.

-/**
- * Implements Armijo Rule Line search along the projection arc (Non-Linear Programming page 230)
- * To be used with Projected gradient Methods.
- * 
- * Recall that armijo tries successive step sizes alpha until the sufficient decrease is satisfied:
- * f(x+alpha*direction) < f(x) + alpha*c1*grad(f)*direction
- * 
- * In this case we are optimizing over a convex set X so we must guarantee that the new point stays inside the 
- * constraints.
- * First the direction as to be feasible (inside constraints) and will be define as:
- * d = (x_k_f - x_k) where x_k_f is a feasible point.
- * so the armijo condition can be rewritten as:
- * f(x+alpha(x_k_f - x_k)) < f(x) + c1*grad(f)*(x_k_f - x_k)
- * and x_k_f is defined as:
- * [x_k-alpha*grad(f)]+
- * where []+ mean a projection to the feasibility set.
- * So this means that we take a step on the negative gradient (gradient descent) and then obtain then project
- * that point to the feasibility set. 
- * Note that if the point is already feasible then we are back to the normal armijo rule.

-// (c) Mark Johnson, 24th January 2005
-//
-// modified 6th May 2002 to ensure write/read consistency, fixed 18th July 2002
-// modified 14th July 2002 to include insert() (generic inserter)
-// modified 26th September 2003 to use mapped_type instead of data_type
-// 25th August 2004 added istream >> const char*
-// 24th January 2005 added insert_newkey()
-//
-// Defines:
-//  loop macros foreach, cforeach
-//  dfind (default find function)
-//  afind (find function that asserts key exists)
-//  insert_newkey (inserts a new key into a map)
-//  insert (generic inserter into standard data structures)
-//  disjoint (set operation)
-//  first_lessthan and second_lessthan (compares elements of pairs)

-// Simplified interfaces to STL routines:
-//
-//  includes (simplified interface)
-//  set_intersection (simplified interface)
-//  inserter (simplified interface)
-//  max_element (simplified interface)
-//  min_element (simplified interface)
-//  hash functions for pairs, vectors, lists, slists and maps

-/**
-  Basic thread-pool tools using Boost.Thread.
-  (Jan Botha, 7/2010)
-
-  --Simple usage--
-  Use SimpleWorker.
-    Example, call a function that returns an int in a new thread:
-    typedef boost::function<int()> JobType;
-    JobType job = boost::bind(funcname);
-      //or boost::bind(&class::funcname, this) for a member function
-    SimpleWorker<JobType, int> worker(job);
-    int result = worker.getResult(); //blocks until result is ready
-
-  --Extended usage--
-  Use WorkerPool, which uses Queuemt (a synchronized queue) and Worker.
-  Example:
-    (same context and typedef
-    WorkerPool<JobType, int> pool(num_threads);
-    JobType job = ...
-    pool.addJob(job);
-    ...
-    pool.get_result(); //blocks until all workers are done, returns the some of their results.  
-    
-    Jobs added to a WorkerPool need to be the same type. A WorkerPool instance should not be reused (e.g. adding jobs) after calling get_result().

-# Manages 'generators' --- objects which can do transformation between different
-# target types and contain algorithm for finding transformation from sources to
-# targets.
-#
-# The main entry point to this module is generators.construct rule. It is given
-# a list of source targets, desired target type and a set of properties. It
-# starts by selecting 'viable generators', which have any chances of producing
-# the desired target type with the required properties. Generators are ranked
-# and a set of the most specific ones is selected.
-#
-# The most specific generators have their 'run' methods called, with the
-# properties and list of sources. Each one selects a target which can be
-# directly consumed, and tries to convert the remaining ones to the types it can
-# consume. This is done by recursively calling 'construct' with all consumable
-# types.
-#
-# If the generator has collected all the targets it needs, it creates targets
-# corresponding to result, and returns it. When all generators have been run,
-# results of one of them are selected and returned as a result.
-#
-# It is quite possible for 'construct' to return more targets that it was asked
-# for. For example, if it were asked to generate a target of type EXE, but the
-# only found generator produces both EXE and TDS (file with debug) information.
-# The extra target will be returned.
-#
-# Likewise, when generator tries to convert sources to consumable types, it can
-# get more targets that it was asked for. The question is what to do with extra
-# targets. Boost.Build attempts to convert them to requested types, and attempts
-# that as early as possible. Specifically, this is done after invoking each
-# generator. TODO: An example is needed to document the rationale for trying
-# extra target conversion at that point.
-#
-# In order for the system to be able to use a specific generator instance 'when
-# needed', the instance needs to be registered with the system using
-# generators.register() or one of its related rules. Unregistered generators may
-# only be run explicitly and will not be considered by Boost.Build when when
-# converting between given target types.

-#  Manages 'generators' --- objects which can do transformation between different
-#  target types and contain algorithm for finding transformation from sources
-#  to targets.
-#
-#  The main entry point to this module is generators.construct rule. It is given
-#  a list of source targets, desired target type and a set of properties.
-#  It starts by selecting 'viable generators', which have any chances of producing
-#  the desired target type with the required properties. Generators are ranked and
-#  a set of most specific ones is selected.
-# 
-#  The most specific generators have their 'run' methods called, with the properties
-#  and list of sources. Each one selects target which can be directly consumed, and
-#  tries to convert the remaining ones to the types it can consume. This is done
-#  by recursively calling 'construct' with all consumable types.
-#
-#  If the generator has collected all the targets it needs, it creates targets 
-#  corresponding to result, and returns it. When all generators have been run,
-#  results of one of them are selected and returned as result.
-#
-#  It's quite possible that 'construct' returns more targets that it was asked for.
-#  For example, it was asked to target type EXE, but the only found generators produces
-#  both EXE and TDS (file with debug) information. The extra target will be returned.
-#
-#  Likewise, when generator tries to convert sources to consumable types, it can get
-#  more targets that it was asked for. The question is what to do with extra targets.
-#  Boost.Build attempts to convert them to requested types, and attempts as early as
-#  possible. Specifically, this is done after invoking each generator. (Later I'll 
-#  document the rationale for trying extra target conversion at that point).
-#
-#  That early conversion is not always desirable. Suppose a generator got a source of
-#  type Y and must consume one target of type X_1 and one target of type X_2.
-#  When converting Y to X_1 extra target of type Y_2 is created. We should not try to
-#  convert it to type X_1, because if we do so, the generator will get two targets
-#  of type X_1, and will be at loss as to which one to use. Because of that, the
-#  'construct' rule has a parameter, telling if multiple targets can be returned. If
-#  the parameter is false, conversion of extra targets is not performed.

-# Implements project representation and loading. Each project is represented by:
-#  - a module where all the Jamfile content live.
-#  - an instance of 'project-attributes' class.
-#    (given a module name, can be obtained using the 'attributes' rule)
-#  - an instance of 'project-target' class (from targets.jam)
-#    (given a module name, can be obtained using the 'target' rule)
-#
-# Typically, projects are created as result of loading a Jamfile, which is done
-# by rules 'load' and 'initialize', below. First, module for Jamfile is loaded
-# and new project-attributes instance is created. Some rules necessary for
-# project are added to the module (see 'project-rules' module) at the bottom of
-# this file. Default project attributes are set (inheriting attributes of parent
-# project, if it exists). After that the Jamfile is read. It can declare its own
-# attributes using the 'project' rule which will be combined with any already
-# set attributes.
-#
-# The 'project' rule can also declare a project id which will be associated with
-# the project module.
-#
-# There can also be 'standalone' projects. They are created by calling
-# 'initialize' on an arbitrary module and not specifying their location. After
-# the call, the module can call the 'project' rule, declare main targets and
-# behave as a regular project except that, since it is not associated with any
-# location, it should not declare targets that are not prebuilt.
-#
-# The list of all loaded Jamfile is stored in the .project-locations variable.
-# It is possible to obtain a module name for a location using the 'module-name'
-# rule. Standalone projects are not recorded and can only be referenced using
-# their project id.

-#  Implements project representation and loading.
-#   Each project is represented by 
-#   - a module where all the Jamfile content live. 
-#   - an instance of 'project-attributes' class.
-#     (given module name, can be obtained by 'attributes' rule)
-#   - an instance of 'project-target' class (from targets.jam)
-#     (given a module name, can be obtained by 'target' rule)
-#
-#  Typically, projects are created as result of loading Jamfile, which is
-#  do by rules 'load' and 'initialize', below. First, module for Jamfile
-#  is loaded and new project-attributes instance is created. Some rules
-#  necessary for project are added to the module (see 'project-rules' module)
-#  at the bottom of this file.
-#  Default project attributes are set (inheriting attributes of parent project, if
-#  it exists). After that, Jamfile is read. It can declare its own attributes,
-#  via 'project' rule, which will be combined with already set attributes.
-#
-#
-#  The 'project' rule can also declare project id, which will be associated with 
-#  the project module.
-#
-#  There can also be 'standalone' projects. They are created by calling 'initialize'
-#  on arbitrary module, and not specifying location. After the call, the module can
-#  call 'project' rule, declare main target and behave as regular projects. However,
-#  since it's not associated with any location, it's better declare only prebuilt 
-#  targets.
-#
-#  The list of all loaded Jamfile is stored in variable .project-locations. It's possible
-#  to obtain module name for a location using 'module-name' rule. The standalone projects
-#  are not recorded, the only way to use them is by project id.

-# Class for storing a set of properties.
-#
-#   There is 1<->1 correspondence between identity and value. No two instances
-# of the class are equal. To maintain this property, the 'property-set.create'
-# rule should be used to create new instances. Instances are immutable.
-#
-#   Each property is classified with regard to its effect on build results.
-# Incidental properties have no effect on build results, from Boost.Build's
-# point of view. Others are either free, or non-free and we refer to non-free
-# ones as 'base'. Each property belongs to exactly one of those categories.
-#
-#   It is possible to get a list of properties belonging to each category as
-# well as a list of properties with a specific attribute.
-#
-#   Several operations, like and refine and as-path are provided. They all use
-# caching whenever possible.

-# Supports 'abstract' targets, which are targets explicitly defined in a
-# Jamfile.
-#
-# Abstract targets are represented by classes derived from 'abstract-target'
-# class. The first abstract target is 'project-target', which is created for
-# each Jamfile, and can be obtained by the 'target' rule in the Jamfile's module
-# (see project.jam).
-#
-# Project targets keep a list of 'main-target' instances. A main target is what
-# the user explicitly defines in a Jamfile. It is possible to have several
-# definitions for a main target, for example to have different lists of sources
-# for different platforms. So, main targets keep a list of alternatives.
-#
-# Each alternative is an instance of 'abstract-target'. When a main target
-# subvariant is defined by some rule, that rule will decide what class to use,
-# create an instance of that class and add it to the list of alternatives for
-# the main target.
-#
-# Rules supplied by the build system will use only targets derived from
-# 'basic-target' class, which will provide some default behaviour. There will be
-# different classes derived from it such as 'make-target', created by the 'make'
-# rule, and 'typed-target', created by rules such as 'exe' and 'lib'.

-#   Supports 'abstract' targets, which are targets explicitly defined in Jamfile.
-#
-#   Abstract targets are represented by classes derived from 'AbstractTarget' class. 
-#   The first abstract target is 'project_target', which is created for each
-#   Jamfile, and can be obtained by the 'target' rule in the Jamfile's module.
-#   (see project.jam). 
-#
-#   Project targets keep a list of 'MainTarget' instances.
-#   A main target is what the user explicitly defines in a Jamfile. It is
-#   possible to have several definitions for a main target, for example to have
-#   different lists of sources for different platforms. So, main targets
-#   keep a list of alternatives.
-#
-#   Each alternative is an instance of 'AbstractTarget'. When a main target
-#   subvariant is defined by some rule, that rule will decide what class to
-#   use, create an instance of that class and add it to the list of alternatives
-#   for the main target.
-#
-#   Rules supplied by the build system will use only targets derived
-#   from 'BasicTarget' class, which will provide some default behaviour.
-#   There will be two classes derived from it, 'make-target', created by the
-#   'make' rule, and 'TypedTarget', created by rules such as 'exe' and 'dll'.

-# Polymorphic class system built on top of core Jam facilities.
-#
-# Classes are defined by 'class' keywords::
-#
-#     class myclass
-#     {
-#         rule __init__ ( arg1 )     # constructor
-#         {

-#         {
-#             return $(self.attribute) ;
-#         }
-#     }
-#
-# The __init__ rule is the constructor, and sets member variables.
-#
-# New instances are created by invoking [ new <class> <args...> ]:
-#
-#     local x = [ new myclass foo ] ;        # x is a new myclass object
-#     assert.result foo : [ $(x).method1 ] ; # $(x).method1 returns "foo"
-#
-# Derived class are created by mentioning base classes in the declaration::
-#
-#     class derived : myclass
-#     {
-#          rule __init__ ( arg )
-#          {
-#              myclass.__init__ $(arg) ;  # call base __init__

-#              return $(self.attribute)XXX ;
-#          }
-#     }
-#
-# All methods operate virtually, replacing behavior in the base classes. For
-# example::

-#  This module defines rules to handle generation of documentation
-#  from BoostBook sources.
-#
-#  The type of output is controlled by the <format> feature which can
-#  have the following values::
-#
-#   * html: Generates html documention.  This is the default.
-#   * xhtml: Generates xhtml documentation
-#   * htmlhelp: Generates html help output.
-#   * onehtml: Generates a single html page.
-#   * man: Generates man pages.
-#   * pdf: Generates pdf documentation.
-#   * ps: Generates postscript output.
-#   * docbook: Generates docbook XML.
-#   * fo: Generates XSL formating objects.
-#   * tests: Extracts test cases from the boostbook XML.
-#
-#  format is an implicit feature, so typing pdf on the command
-#  line (for example) is a short-cut for format=pdf.

-# Configurations
-#
-# The following class helps to manage toolset configurations. Each configuration
-# has a unique ID and one or more parameters. A typical example of a unique ID
-# is a condition generated by 'common.check-init-parameters' rule. Other kinds
-# of IDs can be used. Parameters may include any details about the configuration
-# like 'command', 'path', etc.
-#
-# A toolset configuration may be in one of the following states:
-#
-#   - registered
-#       Configuration has been registered (e.g. explicitly or by auto-detection
-#       code) but has not yet been marked as used, i.e. 'toolset.using' rule has
-#       not yet been called for it.
-#   - used
-#       Once called 'toolset.using' rule marks the configuration as 'used'.
-#
-# The main difference between the states above is that while a configuration is
-# 'registered' its options can be freely changed. This is useful in particular
-# for autodetection code - all detected configurations may be safely overwritten
-# by user code.

-class Configurations(object):
-    """
-        This class helps to manage toolset configurations. Each configuration
-        has a unique ID and one or more parameters. A typical example of a unique ID
-        is a condition generated by 'common.check-init-parameters' rule. Other kinds
-        of IDs can be used. Parameters may include any details about the configuration
-        like 'command', 'path', etc.
-

-
-        - registered
-              Configuration has been registered (e.g. by autodetection code) but has
-              not yet been marked as used, i.e. 'toolset.using' rule has not yet been
-              called for it.
-          - used
-              Once called 'toolset.using' rule marks the configuration as 'used'.
-
-        The main difference between the states above is that while a configuration is
-        'registered' its options can be freely changed. This is useful in particular
-        for autodetection code - all detected configurations may be safely overwritten

-        # messes up the executed export command which then reports that the

-        # extra \r character getting interpreted as a part of the variable name.
-        #
-        #   Several ideas pop to mind on how to fix this:
-        #     * One way would be to separate the commands using the ; shell
-        #       command separator. This seems like the quickest possible
-        #       solution but I do not know whether this would break code on any
-        #       platforms I I have no access to.
-        #     * Another would be to not use the terminating $(nl) but that would
-        #       require updating all the using code so it does not simply
-        #       prepend this variable to its own commands.
-        #     * I guess the cleanest solution would be to update Boost Jam to
-        #       allow explicitly specifying \n & \r characters in its scripts

-# This module defines rules to handle generation of various outputs from source

-#
-# * Source -> Doxygen XML -> BoostBook XML
-# * Source -> Doxygen HTML
-#
-# The type of transformation is selected based on the target requested. For
-# BoostBook XML, the default, specifying a target with an ".xml" suffix, or an
-# empty suffix, will produce a <target>.xml and <target>.boostbook. For Doxygen
-# HTML specifying a target with an ".html" suffix will produce a directory
-# <target> with the Doxygen html files, and a <target>.html file redirecting to
-# that directory.

-#  This module support GNU gettext internationalization utilities.
-#
-#  It provides two main target rules: 'gettext.catalog', used for
-#  creating machine-readable catalogs from translations files, and
-#  'gettext.update', used for update translation files from modified
-#  sources.
-#
-#  To add i18n support to your application you should follow these
-#  steps.
-#
-#  - Decide on a file name which will contain translations and
-#  what main target name will be used to update it. For example::
-#
-#    gettext.update update-russian : russian.po a.cpp my_app ;
-#
-#  - Create the initial translation file by running::
-#
-#    bjam update-russian
-#
-#  - Edit russian.po. For example, you might change fields like LastTranslator.
-#
-#  - Create a main target for final message catalog::
-#
-#    gettext.catalog russian : russian.po ;
-#
-#  The machine-readable catalog will be updated whenever you update
-#  "russian.po". The "russian.po" file will be updated only on explicit
-#  request. When you're ready to update translations, you should
-#
-#  - Run::
-#
-#    bjam update-russian
-#
-#  - Edit "russian.po" in appropriate editor.
-#
-#  The next bjam run will convert "russian.po" into machine-readable form.
-#
-#  By default, translations are marked by 'i18n' call. The 'gettext.keyword'
-#  feature can be used to alter this.

-# Notes on this toolset:
-#
-# - Because of very subtle issues with the default ansi mode, strict_ansi mode
-#   is used for compilation. One example of things that don't work correctly in
-#   the default ansi mode is overload resolution of function templates when
-#   mixed with non-template functions.
-#
-# - For template instantiation "-timplicit_local" is used. Previously,
-#   "-tlocal" has been tried to avoid the need for a template repository
-#   but this doesn't work with manually instantiated templates. "-tweak"
-#   has not been used to avoid the stream of warning messages issued by
-#   ar or ld when creating a library or linking an application.
-#
-# - Debug symbols are generated with "-g3", as this works both in debug and
-#   release mode. When compiling C++ code without optimization, we additionally
-#   use "-gall", which generates full symbol table information for all classes,
-#   structs, and unions. As this turns off optimization, it can't be used when
-#   optimization is needed.

-# Support for the Message Passing Interface (MPI)
-#
-# (C) Copyright 2005, 2006 Trustees of Indiana University
-# (C) Copyright 2005 Douglas Gregor
-#
-# Distributed under the Boost Software License, Version 1.0. (See accompanying 
-# file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt.)
-#
-# Authors: Douglas Gregor
-#          Andrew Lumsdaine
-#
-# ==== MPI Configuration ====
-# 
-# For many users, MPI support can be enabled simply by adding the following 
-# line to your user-config.jam file:
-#
-#   using mpi ;
-#
-# This should auto-detect MPI settings based on the MPI wrapper compiler in 
-# your path, e.g., "mpic++". If the wrapper compiler is not in your path, or
-# has a different name, you can pass the name of the wrapper compiler as the
-# first argument to the mpi module:
-#
-#   using mpi : /opt/mpich2-1.0.4/bin/mpiCC ;
-#
-# If your MPI implementation does not have a wrapper compiler, or the MPI 
-# auto-detection code does not work with your MPI's wrapper compiler,
-# you can pass MPI-related options explicitly via the second parameter to the 
-# mpi module:
-#
-#    using mpi : : <find-shared-library>lammpio <find-shared-library>lammpi++
-#                  <find-shared-library>mpi <find-shared-library>lam 
-#                  <find-shared-library>dl ;
-#
-# To see the results of MPI auto-detection, pass "--debug-configuration" on
-# the bjam command line.
-#
-# The (optional) fourth argument configures Boost.MPI for running
-# regression tests. These parameters specify the executable used to
-# launch jobs (default: "mpirun") followed by any necessary arguments
-# to this to run tests and tell the program to expect the number of
-# processors to follow (default: "-np").  With the default parameters,
-# for instance, the test harness will execute, e.g.,
-#  
-#    mpirun -np 4 all_gather_test
-#
-# ==== Linking Against the MPI Libraries ===
-#
-# To link against the MPI libraries, import the "mpi" module and add the 
-# following requirement to your target:
-# 
-#   <library>/mpi//mpi 
-#
-# Since MPI support is not always available, you should check 
-# "mpi.configured" before trying to link against the MPI libraries.

-# Initialize a specific toolset version configuration. As the result, path to
-# compiler and, possible, program names are set up, and will be used when that
-# version of compiler is requested. For example, you might have:
-#
-#    using msvc : 6.5 : cl.exe ;
-#    using msvc : 7.0 : Y:/foo/bar/cl.exe ;
-#
-# The version parameter may be ommited:
-#
-#    using msvc : : Z:/foo/bar/cl.exe ;
-#
-# The following keywords have special meanings when specified as versions:
-#   - all     - all detected but not yet used versions will be marked as used
-#               with their default options.
-#   - default - this is an equivalent to an empty version.
-#
-# Depending on a supplied version, detected configurations and presence 'cl.exe'
-# in the path different results may be achieved. The following table describes
-# the possible scenarios:
-#
-#                                      Nothing            "x.y"
-# Passed   Nothing       "x.y"         detected,          detected,
-# version  detected      detected      cl.exe in path     cl.exe in path
-#
-# default  Error         Use "x.y"     Create "default"   Use "x.y"
-# all      None          Use all       None               Use all
-# x.y      -             Use "x.y"     -                  Use "x.y"
-# a.b      Error         Error         Create "a.b"       Create "a.b"
-#
-# "x.y" - refers to a detected version;
-# "a.b" - refers to an undetected version.

-# seem to overlap in duties. Remove this duplication. This seems to be related

-# - cmd-or-prefix: Preferably, a command that invokes a Python interpreter.
-#   Alternatively, the installation prefix for Python libraries and includes. If
-#   empty, will be guessed from the version, the platform's installation
-#   patterns, and the python executables that can be found in PATH.
-#
-# - includes: the include path to Python headers. If empty, will be guessed.
-#
-# - libraries: the path to Python library binaries. If empty, will be guessed.
-#   On MacOS/Darwin, you can also pass the path of the Python framework.

-# - extension-suffix: A string to append to the name of extension modules before
-#   the true filename extension.  Ordinarily we would just compute this based on

-# Qt4 library support module
-#
-# The module attempts to auto-detect QT installation location from QTDIR
-# environment variable; failing that, installation location can be passed as
-# argument:
-#
-# toolset.using qt4 : /usr/local/Trolltech/Qt-4.0.0 ;
-#
-# The module supports code generation from .ui and .qrc files, as well as
-# running the moc preprocessor on headers. Note that you must list all your
-# moc-able headers in sources.
-#
-# Example:
-#
-#     exe myapp : myapp.cpp myapp.h myapp.ui myapp.qrc
-#                 /qt4//QtGui /qt4//QtNetwork ;
-#
-# It's also possible to run moc on cpp sources:
-#
-#   import cast ;
-#
-#   exe myapp : myapp.cpp [ cast _ moccable-cpp : myapp.cpp ] /qt4//QtGui ;
-#
-# When moccing source file myapp.cpp you need to include "myapp.moc" from
-# myapp.cpp. When moccing .h files, the output of moc will be automatically
-# compiled and linked in, you don't need any includes.
-#
-# This is consistent with Qt guidelines:
-# http://doc.trolltech.com/4.0/moc.html

-# This toolset defines a generator to translate QuickBook to BoostBook. It can
-# be used to generate nice (!) user documentation in different formats
-# (pdf/html/...), from a single text file with simple markup.
-#
-# The toolset defines the QUICKBOOK type (file extension 'qbk') and
-# a QUICKBOOK to XML (BOOSTBOOK) generator.
-#
-#
-#   ===========================================================================
-#   Q & A
-#   ===========================================================================
-#
-#   If you don't know what this is all about, some Q & A will hopefully get you
-#   up to speed with QuickBook and this toolset.
-#
-#
-#   What is QuickBook ?
-#
-#       QuickBook is a WikiWiki style documentation tool geared towards C++
-#       documentation using simple rules and markup for simple formatting tasks.
-#       QuickBook extends the WikiWiki concept. Like the WikiWiki, QuickBook
-#       documents are simple text files. A single QuickBook document can
-#       generate a fully linked set of nice HTML and PostScript/PDF documents
-#       complete with images and syntax-colorized source code.
-#
-#
-#   Where can I get QuickBook ?
-#
-#       Quickbook can be found in Boost's repository, under the tools/quickbook
-#       directory it was added there on Jan 2005, some time after the release of
-#       Boost v1.32.0 and has been an integral part of the Boost distribution
-#       since v1.33.
-#
-#       Here's a link to the SVN repository:
-#           https://svn.boost.org/svn/boost/trunk/tools/quickbook
-#
-#       And to QuickBook's QuickBook-generated docs:
-#           http://www.boost.org/doc/libs/release/tools/quickbook/index.html
-#
-#
-#   How do I use QuickBook and this toolset in my projects ?
-#
-#       The minimal example is:
-#
-#           using boostbook ;
-#           import quickbook ;
-#
-#           boostbook my_docs : my_docs_source.qbk ;
-#
-#       where my_docs is a target name and my_docs_source.qbk is a QuickBook
-#       file. The documentation format to be generated is determined by the
-#       boostbook toolset. By default html documentation should be generated,
-#       but you should check BoostBook's docs to be sure.
-#
-#
-#   What do I need ?
-#
-#       You should start by setting up the BoostBook toolset. Please refer to
-#       boostbook.jam and the BoostBook documentation for information on how to
-#       do this.
-#
-#       A QuickBook executable is also needed. The toolset will generate this
-#       executable if it can find the QuickBook sources. The following
-#       directories will be searched:
-#
-#           BOOST_ROOT/tools/quickbook/
-#           BOOST_BUILD_PATH/../../quickbook/
-#
-#       (BOOST_ROOT and BOOST_BUILD_PATH are environment variables)
-#
-#       If QuickBook sources are not found the toolset will then try to use
-#       the shell command 'quickbook'.
-#
-#
-#   How do I provide a custom QuickBook executable ?
-#
-#       You may put the following in your user-config.jam or site-config.jam:
-#
-#           using quickbook : /path/to/quickbook ;
-#
-#       or, if 'quickbook' can be found in your PATH,
-#
-#           using quickbook : quickbook ;
-#
-#
-#   For convenience three alternatives are tried to get a QuickBook executable:
-#
-#       1.  If the user points us to the a QuickBook executable, that is used.
-#
-#       2.  Otherwise, we search for the QuickBook sources and compile QuickBook
-#           using the default toolset.
-#
-#       3.  As a last resort, we rely on the shell for finding 'quickbook'.

-# This module implements regression testing framework. It declares a number of
-# main target rules which perform some action and, if the results are OK,
-# creates an output file.
-#
-# The exact list of rules is:
-# 'compile'       -- creates .test file if compilation of sources was
-#                    successful.
-# 'compile-fail'  -- creates .test file if compilation of sources failed.
-# 'run'           -- creates .test file is running of executable produced from
-#                    sources was successful. Also leaves behind .output file
-#                    with the output from program run.
-# 'run-fail'      -- same as above, but .test file is created if running fails.
-#
-# In all cases, presence of .test file is an indication that the test passed.
-# For more convenient reporting, you might want to use C++ Boost regression
-# testing utilities (see http://www.boost.org/more/regression.html).
-#
-# For historical reason, a 'unit-test' rule is available which has the same
-# syntax as 'exe' and behaves just like 'run'.
-
-# Things to do:
-#  - Teach compiler_status handle Jamfile.v2.
-# Notes:
-#  - <no-warn> is not implemented, since it is Como-specific, and it is not
-#    clear how to implement it
-#  - std::locale-support is not implemented (it is used in one test).

-# This module implements regression testing framework. It declares a number of
-# main target rules which perform some action and, if the results are OK,
-# creates an output file.
-#
-# The exact list of rules is:
-# 'compile'       -- creates .test file if compilation of sources was
-#                    successful.
-# 'compile-fail'  -- creates .test file if compilation of sources failed.
-# 'run'           -- creates .test file is running of executable produced from
-#                    sources was successful. Also leaves behind .output file
-#                    with the output from program run.
-# 'run-fail'      -- same as above, but .test file is created if running fails.
-#
-# In all cases, presence of .test file is an indication that the test passed.
-# For more convenient reporting, you might want to use C++ Boost regression
-# testing utilities (see http://www.boost.org/more/regression.html).
-#
-# For historical reason, a 'unit-test' rule is available which has the same
-# syntax as 'exe' and behaves just like 'run'.
-
-# Things to do:
-#  - Teach compiler_status handle Jamfile.v2.
-# Notes:
-#  - <no-warn> is not implemented, since it is Como-specific, and it is not
-#    clear how to implement it
-#  - std::locale-support is not implemented (it is used in one test).

-# Supports the zlib library
-#
-# After 'using zlib', the following targets are available:
-#
-# /zlib//zlib -- The zlib library
-
-
-# In addition to direct purpose of supporting zlib, this module also
-# serves as canonical example of how third-party condiguration works
-# in Boost.Build. The operation is as follows
-#
-# - For each 'using zlib : condition ... : ...' we create a target alternative
-#   for zlib, with the specified condition.
-# - There's one target alternative for 'zlib' with no specific condition
-#   properties. 
-#
-# Two invocations of 'using zlib' with the same condition but different
-# properties are not permitted, e.g.:
-#
-#   using zlib : condition <target-os>windows : include foo ;
-#   using zlib : condition <target-os>windows : include bar ;
-#
-# is in error. One exception is for empty condition, 'using' without any
-# parameters is overridable. That is:
-#
-#   using zlib ;
-#   using zlib : include foo ;
-# 
-# Is OK then the first 'using' is ignored. Likewise if the order of the statements
-# is reversed.
-#
-# When 'zlib' target is built, a target alternative is selected as usual for
-# Boost.Build. The selected alternative is a custom target class, which:
-#
-# - calls ac.find-include-path to find header path. If explicit path is provided
-#   in 'using', only that path is checked, and if no header is found there, error
-#   is emitted. Otherwise, we check a directory specified using ZLIB_INCLUDE
-#   environment variable, and failing that, in standard directories.
-#   [TODO: document sysroot handling]
-# - calls ac.find-library to find the library, in an identical fashion.

-#   This file is used to configure your Boost.Build installation. You can modify
-# this file in place, or you can place it in a permanent location so that it
-# does not get overwritten should you get a new version of Boost.Build. See:
-#
-#   http://www.boost.org/boost-build2/doc/html/bbv2/overview/configuration.html
-#
-# for documentation about possible permanent locations.
-
-#   This file specifies which toolsets (C++ compilers), libraries, and other
-# tools are available. Often, you should be able to just uncomment existing
-# example lines and adjust them to taste. The complete list of supported tools,
-# and configuration instructions can be found at:
-#
-#   http://boost.org/boost-build2/doc/html/bbv2/reference/tools.html
-#
-
-#   This file uses Jam language syntax to describe available tools. Mostly,
-# there are 'using' lines, that contain the name of the used tools, and
-# parameters to pass to those tools -- where paremeters are separated by
-# semicolons. Important syntax notes:
-#
-#   - Both ':' and ';' must be separated from other tokens by whitespace
-#   - The '\' symbol is a quote character, so when specifying Windows paths you
-#     should use '/' or '\\' instead.
-#
-# More details about the syntax can be found at:

-#  This module defines a class which allows to order arbitrary object with

-#
-#  The primary use case is the gcc toolset, which is sensitive to library order:
-#  if library 'a' uses symbols from library 'b', then 'a' must be present before
-#  'b' on the linker's command line.
-#
-#  This requirement can be lifted for gcc with GNU ld, but for gcc with Solaris
-#  LD (and for Solaris toolset as well), the order always matters.
-#
-#  So, we need to store order requirements and then order libraries according to
-#  them. It is not possible to use the dependency graph as order requirements.
-#  What we need is a "use symbols" relationship while dependency graph provides
-#  the "needs to be updated" relationship.
-#
-#  For example::
-#    lib a : a.cpp b;
-#    lib b ;
-#
-#  For static linking, library 'a' need not depend on 'b'. However, it should
-#  still come before 'b' on the command line.

-        
-        This requirement can be lifted for gcc with GNU ld, but for gcc with
-        Solaris LD (and for Solaris toolset as well), the order always matters.
-        
-        So, we need to store order requirements and then order libraries
-        according to them. It it not possible to use dependency graph as
-        order requirements. What we need is "use symbols" relationship
-        while dependency graph provides "needs to be updated" relationship.
-        
-        For example::
-          lib a : a.cpp b;
-          lib b ;
-        
-        For static linking, the 'a' library need not depend on 'b'. However, it
-        still should come before 'b' on the command line.

-# Brief review of the jam language:
-#
-# Statements:
-#   rule RULE - statements to process a rule
-#   actions RULE - system commands to carry out target update
-#
-# Modifiers on actions:
-#   together - multiple instances of same rule on target get executed
-#          once with their sources ($(>)) concatenated
-#   updated - refers to updated sources ($(>)) only
-#   ignore - ignore return status of command
-#   quietly - don't trace its execution unless verbose
-#   piecemeal - iterate command each time with a small subset of $(>)
-#   existing - refers to currently existing sources ($(>)) only
-#   bind vars - subject to binding before expanding in actions
-#
-# Special rules:
-#   ALWAYS - always build a target
-#   DEPENDS - builds the dependency graph
-#   ECHO - blurt out targets on stdout
-#   EXIT - blurt out targets and exit
-#   INCLUDES - marks sources as headers for target (a codependency)
-#   NOCARE - don't panic if the target can't be built
-#   NOUPDATE - create the target if needed but never update it
-#   NOTFILE - ignore the timestamp of the target (it's not a file)
-#   TEMPORARY - target need not be present if sources haven't changed
-#
-# Special variables set by jam:
-#   $(<) - targets of a rule (to the left of the :)
-#   $(>) - sources of a rule (to the right of the :)
-#   $(xxx) - true on xxx (UNIX, VMS, NT, OS2, MAC)
-#   $(OS) - name of OS - varies wildly
-#   $(JAMVERSION) - version number (2.3)
-#
-# Special variables used by jam:
-#   SEARCH - where to find something (used during binding and actions)
-#   LOCATE - where to plop something not found with SEARCH
-#   HDRRULE - rule to call to handle include files
-#   HDRSCAN - egrep regex to extract include files
-#
-# Special targets:
-#   all - default if none given on command line

-     * This wrapper is a workaround for a funny _popen() feature on Windows
-     * where it eats external quotes in some cases. The bug seems to be related
-     * to the quote stripping functionality used by the Windows cmd.exe
-     * interpreter when its /S is not specified.
-     *
-     * Cleaned up quote from the cmd.exe help screen as displayed on Windows XP
-     * SP3:
-     *
-     *   1. If all of the following conditions are met, then quote characters on
-     *      the command line are preserved:
-     *
-     *       - no /S switch
-     *       - exactly two quote characters
-     *       - no special characters between the two quote characters, where
-     *         special is one of: &<>()@^|
-     *       - there are one or more whitespace characters between the two quote
-     *         characters
-     *       - the string between the two quote characters is the name of an
-     *         executable file.
-     *
-     *   2. Otherwise, old behavior is to see if the first character is a quote
-     *      character and if so, strip the leading character and remove the last
-     *      quote character on the command line, preserving any text after the
-     *      last quote character.
-     *
-     * This causes some commands containing quotes not to be executed correctly.
-     * For example:
-     *
-     *   "\Long folder name\aaa.exe" --name="Jurko" --no-surname
-     *
-     * would get its outermost quotes stripped and would be executed as:
-     *
-     *   \Long folder name\aaa.exe" --name="Jurko --no-surname
-     *
-     * which would report an error about '\Long' not being a valid command.
-     *
-     * cmd.exe help seems to indicate it would be enough to add an extra space
-     * character in front of the command to avoid this but this does not work,
-     * most likely due to the shell first stripping all leading whitespace
-     * characters from the command.
-     *
-     * Solution implemented here is to quote the whole command in case it
-     * contains any quote characters. Note thought this will not work correctly
-     * should Windows ever 'fix' this feature.
-     *                                               (03.06.2008.) (Jurko)

-Description: Build tool 
- Boost.Jam is a portable build tool with its own interpreted language, which 
- allows to implement rather complex logic in a readable way and without 
- resorting to external programs. It is a descendant of Jam/MR tool modified to 
- suit the needs of Boost.Build. In particular, modules and rule parameters
- were added, as well as several new builtins.

-    <para>Jam recursively builds target files from source files, using

-    The default Jambase is compiled into jam and provides a

-    "Jamfile" to enumerate actual targets and sources.</para>

-/*
- * execunix.c - execute a shell script on UNIX/WinNT/OS2/AmigaOS
- *
- * If $(JAMSHELL) is defined, uses that to formulate execvp()/spawnvp().
- * The default is:
- *
- *  /bin/sh -c %        [ on UNIX/AmigaOS ]
- *  cmd.exe /c %        [ on OS2/WinNT ]
- *
- * Each word must be an individual element in a jam variable value.
- *
- * In $(JAMSHELL), % expands to the command string and ! expands to the slot
- * number (starting at 1) for multiprocess (-j) invocations. If $(JAMSHELL) does
- * not include a %, it is tacked on as the last argument.
- *
- * Do not just set JAMSHELL to /bin/sh or cmd.exe - it will not work!
- *
- * External routines:
- *  exec_cmd() - launch an async command execution.
- *  exec_wait() - wait and drive at most one execution completion.
- *
- * Internal routines:
- *  onintr() - bump intr to note command interruption.
- *
- * 04/08/94 (seiwald) - Coherent/386 support added.
- * 05/04/94 (seiwald) - async multiprocess interface
- * 01/22/95 (seiwald) - $(JAMSHELL) support
- * 06/02/97 (gsar)    - full async multiprocess support for Win32

- *
- * If the command is multi-line, or longer than WRTLEN, we write the command
- * block to a temp file, splitting long lines (using "-" at the end of the line
- * to indicate contiuation), and then source that temp file. We use special
- * logic to make sure we do not continue in the middle of a quoted string.
- *
- * 05/04/94 (seiwald) - async multiprocess interface; noop on VMS
- * 12/20/96 (seiwald) - rewritten to handle multi-line commands well
- * 01/14/96 (seiwald) - do not put -'s between "'s

- *
- * Roughly, the modules are:
- *
- *  builtins.c - jam's built-in rules
- *  command.c - maintain lists of commands
- *  compile.c - compile parsed jam statements
- *  execunix.c - execute a shell script on UNIX
- *  execvms.c - execute a shell script, ala VMS
- *  expand.c - expand a buffer, given variable values
- *  file*.c - scan directories and archives on *
- *  hash.c - simple in-memory hashing routines
- *  hdrmacro.c - handle header file parsing for filename macro definitions
- *  headers.c - handle #includes in source files
- *  jambase.c - compilable copy of Jambase
- *  jamgram.y - jam grammar
- *  lists.c - maintain lists of strings
- *  make.c - bring a target up to date, once rules are in place
- *  make1.c - execute command to bring targets up to date
- *  newstr.c - string manipulation routines
- *  option.c - command line option processing
- *  parse.c - make and destroy parse trees as driven by the parser
- *  path*.c - manipulate file names on *
- *  hash.c - simple in-memory hashing routines
- *  regexp.c - Henry Spencer's regexp
- *  rules.c - access to RULEs, TARGETs, and ACTIONs
- *  scan.c - the jam yacc scanner
- *  search.c - find a target along $(SEARCH) or $(LOCATE)
- *  timestamp.c - get the timestamp of a file or archive member
- *  variable.c - handle jam multi-element variables
- *
- * 05/04/94 (seiwald) - async multiprocess (-j) support
- * 02/08/95 (seiwald) - -n implies -d2.
- * 02/22/95 (seiwald) - -v for version info.
- * 09/11/00 (seiwald) - PATCHLEVEL folded into VERSION.
- * 01/10/01 (seiwald) - pathsys.h split from filesys.h

- * jamgram.yy - jam grammar
- *
- * 04/13/94 (seiwald) - added shorthand L0 for null list pointer
- * 06/01/94 (seiwald) - new 'actions existing' does existing sources
- * 08/23/94 (seiwald) - Support for '+=' (append to variable)
- * 08/31/94 (seiwald) - Allow ?= as alias for "default =".
- * 09/15/94 (seiwald) - if conditionals take only single arguments, so
- *			that 'if foo == bar' gives syntax error (use =).
- * 02/11/95 (seiwald) - when scanning arguments to rules, only treat
- *			punctuation keywords as keywords.  All arg lists
- *			are terminated with punctuation keywords.
- *
- * 09/11/00 (seiwald) - Support for function calls:
- *
- *		Rules now return lists (LIST *), rather than void.
- *
- *		New "[ rule ]" syntax evals rule into a LIST.
- *
- *		Lists are now generated by compile_list() and
- *		compile_append(), and any other rule that indirectly
- *		makes a list, rather than being built directly here,
- *		so that lists values can contain rule evaluations.
- *
- *		New 'return' rule sets the return value, though
- *		other statements also may have return values.
- *
- *		'run' production split from 'block' production so
- *		that empty blocks can be handled separately.

- *
- * External routines:
- *
- *  make1() - execute commands to update a TARGET and all of its dependencies.

- * Internal routines, the recursive/asynchronous command executors:
- *
- *  make1a()     - recursively traverse dependency target tree, calling make1b().
- *  make1atail() - started processing all dependencies so go on to make1b().
- *  make1b()     - when dependencies are up to date, build target with make1c().
- *  make1c()     - launch target's next command, call parents' make1b() if none.
- *  make1d()     - handle command execution completion and call back make1c().
- *
- * Internal support routines:
- *
- *  make1cmds()     - turn ACTIONS into CMDs, grouping, splitting, etc.
- *  make1list()     - turn a list of targets into a LIST, for $(<) and $(>).
- *  make1settings() - for vars that get bound values, build up replacement lists.
- *  make1bind()     - bind targets that weren't bound in dependency analysis.
- *
- * 04/16/94 (seiwald) - Split from make.c.
- * 04/21/94 (seiwald) - Handle empty "updated" actions.
- * 05/04/94 (seiwald) - async multiprocess (-j) support.
- * 06/01/94 (seiwald) - new 'actions existing' does existing sources.
- * 12/20/94 (seiwald) - NOTIME renamed NOTFILE.
- * 01/19/95 (seiwald) - distinguish between CANTFIND/CANTMAKE targets.
- * 01/22/94 (seiwald) - pass per-target JAMSHELL down to exec_cmd().
- * 02/28/95 (seiwald) - Handle empty "existing" actions.

-  Independent implementation of MD5 (RFC 1321).
-
-  This code implements the MD5 Algorithm defined in RFC 1321, whose
-  text is available at
-	http://www.ietf.org/rfc/rfc1321.txt
-  The code is derived from the text of the RFC, including the test suite
-  (section A.5) but excluding the rest of Appendix A.  It does not include
-  any code or documentation that is identified in the RFC as being
-  copyrighted.
-
-  The original and principal author of md5.c is L. Peter Deutsch
-  <ghost@aladdin.com>.  Other authors are noted in the change history
-  that follows (in reverse chronological order):
-
-  2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
-	either statically or dynamically; added missing #include <string.h>
-	in library.
-  2002-03-11 lpd Corrected argument list for main(), and added int return
-	type, in test program and T value program.
-  2002-02-21 lpd Added missing #include <stdio.h> in test program.
-  2000-07-03 lpd Patched to eliminate warnings about "constant is
-	unsigned in ANSI C, signed in traditional"; made test program
-	self-checking.
-  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
-  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
-  1999-05-03 lpd Original version.

-  that follows (in reverse chronological order):
-
-  2002-04-13 lpd Removed support for non-ANSI compilers; removed
-	references to Ghostscript; clarified derivation from RFC 1321;
-	now handles byte order either statically or dynamically.
-  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
-  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5);
-	added conditionalization for C++ compilation from Martin

- * The "internal use only" fields in regexp.h are present to pass info from

- *  reganch  is the match anchored (at beginning-of-line only)?
- *  regmust  string (pointer into program) that match must include, or NULL.
- *  regmlen  length of regmust string.
- *
- * Regstart and reganch permit very fast decisions on suitable starting points
- * for a match, cutting down the work a lot.  Regmust permits fast rejection of
- * lines that cannot possibly match.  The regmust tests are costly enough that
- * regcomp() supplies a regmust only if the r.e. contains something potentially
- * expensive (at present, the only such thing detected is * or + at the start of
- * the r.e., which can involve a lot of backup). Regmlen is supplied because the

- * Structure for regexp "program". This is essentially a linear encoding of a

- * implement concatenation; a "next" pointer with a BRANCH on both ends of it is
- * connecting two alternatives. [Here we have one of the subtle syntax
- * dependencies: an individual BRANCH, as opposed to a collection of them, is
- * never concatenated with anything because of operator precedence.] The operand
- * of some types of node is a literal string; for others, it is a node leading
- * into a sub-FSM. In particular, the operand of a BRANCH node is the first node
- * of the branch. [NB this is *not* a tree structure: the tail of the branch
- * connects to the thing following the set of BRANCHes.] The opcodes are:

- *      "next" pointer of the last BRANCH in a choice points to the

- *      final "next" pointer of each individual branch points; each

- * BACK     Normal "next" pointers all implicitly point forward; BACK
- *      exists to make loop structures possible.
- *
- * STAR,PLUS    '?', and complex '*' and '+', are implemented as circular
- *      BRANCH structures using BACK.  Simple cases (one character

-
-  The output will be a model that, when run with cdec, will produce
