+# 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.

+#  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.

+#
+# ==== 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.

+# 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:

+         * of the targets getting used before its action completes its work, it
+         * also forces the action to run whenever any of the targets in the

+         * targets that are not up to date.

+         * TODO: Current solution using fake INCLUDES relations may cause
+         * actions to be run when the affected targets are built by multiple
+         * actions. E.g. if we have the following actions registered in the
+         * order specified:
+         *     (I) builds targets A & B
+         *     (II) builds target B
+         * and we want to build a target depending on target A, then both
+         * actions (I) & (II) will be run, even though the second one does not
+         * have any direct relationship to target A. Consider whether this is
+         * desired behaviour or not. It could be that Boost Build should (or
+         * possibly already does) run all actions registered for a given target
+         * if any of them needs to be run in which case our INCLUDES relations
