+# The utitlities of this package are grouped into:
+# <dl><dt>\ref use</dt><dd>help using complex environments and
+# configure the construction environmen correspondingly</dd>
+#
+# <dt>\ref target</dt><dd>simplify building common targest and include
+# enhanced functionality like unit-testing.</dd></dl>
+#
+# Additionally for external use are
+# <dl><dt>MakeEnvironment()</dt><dd>Build construction
+# environment</dd>
+#
+# <dt>GlobSources()</dt><dd>Utility to find source files</dd></dl>
+#
+# All other functions are for internal use only.

+## \defgroup use Predefined Framework Configurators
+#
+# The following framework configurators are used in the top level \c
+# SConstruct file to simplify more complex configurations.
+#
+# Each of the framework configurators introduces additional
+# configuration parameters to \ref sconfig
+
+## \defgroup target Target Helpers
+#
+# To specify standard targets, the following helpers can be used. They
+# automatically integrate several modules (like documentation,
+# unit-testing etc).
+
+## \defgroup builder Builders
+#
+# The SENFSCons framework includes a series of builders. Each builder
+# is defined in it's own package.

+#
+# Configure the use of the <a href="http://www.boost.org">Boost</a>
+# libraries. Most of these libraries are header-only, some however
+# depend on a built library. The library selection is somewhat
+# involved and depends on the threading model and the type of build
+# (debug or final).

+# \par Configuration Parameters:
+# <table class="senf">
+# <tr><td>\c BOOST_INCLUDES</td><td>Include directory.</td></tr>
+# <tr><td>\c BOOST_LIBDIR</td><td>Library directory</td></tr>
+# <tr><td>\c BOOST_VARIANT</td><td>Complete variant specification</td></tr>
+# <tr><td>\c BOOST_TOOLSET</td><td>Toolset to use</td></tr>
+# <tr><td>\c BOOST_RUNTIME</td><td>Runtime to use</td></tr>
+# <tr><td>\c BOOST_DEBUG_RUNTIME</td><td>Explicit debug runtime</td></tr>
+# </table>
+#
+# You can either specify \c BOOST_VARIANT explicitly or specify \c
+# BOOST_TOOLSET and \c BOOST_RUNTIME. If you give \c BOOST_TOOLSET, \c
+# BOOST_RUNTIME defaults to empty and \c BOOST_DEBUG_RUNTIME defaults
+# to \c gd, If \c BOOST_TOOLSET is specified and you have included
+# STLPort support (UseSTLPort()), then \c p is appended to both
+# runtimes.
+#
+# The Boost configuration can get realtively complex. If the boost
+# libraries are provided by the distribution, you probably don't need
+# to specify any parameters. If your configuration is more complex,
+# refer to the <a
+# href="http://www.boost.org/tools/build/v1/build_system.htm">Boost.Build</a>

+# Use <a href="http://www.stlport.org">STLPort</a> as a replacement
+# for the system STL. STLPort has the added feature of providing fully

+# debugging. However, STLPort and Boost interact in a non-trivial way
+# so the configuration is relatively complex. This command does not
+# enforce the use of STLPort, it is only used if available.

+## \brief Build documentation with doxygen
+#
+# The doxygen target helper will build software documentation using
+# the given \a doxyfile (which defaults to \c Doxyfile). The Doxygen
+# builder used supports automatic dependency generation (dependencies
+# are automatically generated from the parameters specified in the \a
+# doxyfile), automatic target emitters (the exact targets created are
+# found parsing the \a doxyfile) and lots of other features. See the
+# Doxygen builder documentation
+#
+# If \a extra_sources are given, the generated documentation will
+# depend on them. This can be used to build images or other
+# supplementary files.
+#
+# The doxygen target helper extends the builder with additional
+# functionality:
+#
+# \li Fix tagfiles by removing namespace entries. These entries only
+# work for namespaces completely defined in a single module. As
+# soon as another module (which references the tagfile) has it's
+# own members in that namespace, the crosslinking will break.
+# \li If \c DOXY_HTML_XSL is defined as a construction environment
+# variable, preprocess all generated html files (if html files are
+# generated) by the given XSLT stylesheet. Since the HTML
+# generated by doxygen is broken, we first filter the code through
+# HTML-\c tidy and filter out some error messages.
+# \li If xml output is generatedwe create files \c bug.xmli and \c
+# todo.xmli which contain all bugs and todo items specified in the
+# sources. The format of these files is much more suited to
+# postprocessing and is a more database like format as the doxygen
+# generated files (which are more presentation oriented). if \c
+# DOXY_XREF_TYPES is given, it will specify the cross reference
+# types to support (defaults to \c bug and \c todo). See <a
+# href="http://www.stack.nl/~dimitri/doxygen/commands.html#cmdxrefitem">\xrefitem</a>
