-# 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.

-#   There is 1<->1 correspondence between identity and value. No two instances

-# 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
-#         {
-#             self.attribute = $(arg1) ;
-#         }
-#
-#         rule method1 ( )           # method
-#         {
-#             return [ method2 ] ;
-#         }
-#
-#         rule method2 ( )           # method
-#         {
-#             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__
-#
-#          }
-#
-#          rule method2 ( )           # method override
-#          {
-#              return $(self.attribute)XXX ;
-#          }
-#     }
-#
-# All methods operate virtually, replacing behavior in the base classes. For
-# example::
-#
-#     local y = [ new derived foo ] ;            # y is a new derived object
-#     assert.result fooXXX : [ $(y).method1 ] ;  # $(y).method1 returns "foo"
-#
-# Each class instance is its own core Jam module. All instance attributes and
-# methods are accessible without additional qualification from within the class
-# instance. All rules imported in class declaration, or visible in base classses
-# are also visible. Base methods are available in qualified form:
-# base-name.method-name. By convention, attribute names are prefixed with
-# "self.".

-#  The type of output is controlled by the <format> feature which can

-#
-#   * html: Generates html documention.  This is the default.
-#   * xhtml: Generates xhtml documentation
-#   * htmlhelp: Generates html help output.

-#   * 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

-# 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.

-        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

-        like 'command', 'path', etc.

-          - used
-              Once called 'toolset.using' rule marks the configuration as 'used'.

-# This module defines rules to handle generation of various outputs from source
-# files documented with doxygen comments. The supported transformations are:
-#
-# * 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.

-# ==== 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"

-# 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"
-#

-# - version -- the version of Python to use. Should be in Major.Minor format,
-#   for example 2.3.  Do not include the subminor version.
-#
-# - 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.
-#
-# - condition: if specified, should be a set of properties that are matched
-#   against the build configuration when Boost.Build selects a Python
-#   configuration to use.
-#
-# - 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
-#   the value of the <python-debugging> feature. However ubuntu's python-dbg
-#   package uses the windows convention of appending _d to debug-build extension
-#   modules. We have no way of detecting ubuntu, or of probing python for the
-#   "_d" requirement, and if you configure and build python using
-#   --with-pydebug, you'll be using the standard *nix convention. Defaults to ""
-#   (or "_d" when targeting windows and <python-debugging> is set).

-# 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

-# 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

-#   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.
-#

-#  This module defines a class which allows to order arbitrary object with
-# regard to arbitrary binary relation.
-#
-#  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.

-
-        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 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.
