+# 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

+          - 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

+#

+# empty suffix, will produce a <target>.xml and <target>.boostbook. For Doxygen

+# <target> with the Doxygen html files, and a <target>.html file redirecting to

+
+#  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.

+#
+# - 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.

+# 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.

+# - 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 ""

+# 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.
