+#!/usr/bin/env python
+# encoding: utf-8
+#
+# partially based on boost.py written by Gernot Vormayr
+# written by Ruediger Sonderfeld <ruediger@c-plusplus.de>, 2008
+# modified by Bjoern Michaelsen, 2008
+# modified by Luca Fossati, 2008
+# rewritten for waf 1.5.1, Thomas Nagy, 2008
+# rewritten for waf 1.6.2, Sylvain Rouquette, 2011
+
+'''
+
+This is an extra tool, not bundled with the default waf binary.
+To add the boost tool to the waf file:
+$ ./waf-light --tools=compat15,boost
+	or, if you have waf >= 1.6.2
+$ ./waf update --files=boost
+
+When using this tool, the wscript will look like:
+
+	def options(opt):
+		opt.load('compiler_cxx boost')
+
+	def configure(conf):
+		conf.load('compiler_cxx boost')
+		conf.check_boost(lib='system filesystem')
+
+	def build(bld):
+		bld(source='main.cpp', target='app', use='BOOST')
+
+Options are generated, in order to specify the location of boost includes/libraries.
+The `check_boost` configuration function allows to specify the used boost libraries.
+It can also provide default arguments to the --boost-static and --boost-mt command-line arguments.
+Everything will be packaged together in a BOOST component that you can use.
+
+When using MSVC, a lot of compilation flags need to match your BOOST build configuration:
+ - you may have to add /EHsc to your CXXFLAGS or define boost::throw_exception if BOOST_NO_EXCEPTIONS is defined.
+   Errors: C4530
+ - boost libraries will try to be smart and use the (pretty but often not useful) auto-linking feature of MSVC
+   So before calling `conf.check_boost` you might want to disabling by adding:
+   	conf.env.DEFINES_BOOST += ['BOOST_ALL_NO_LIB']
+   Errors: 
+ - boost might also be compiled with /MT, which links the runtime statically.
+   If you have problems with redefined symbols, 
+		self.env['DEFINES_%s' % var] += ['BOOST_ALL_NO_LIB']
+		self.env['CXXFLAGS_%s' % var] += ['/MD', '/EHsc']
+Passing `--boost-linkage_autodetect` might help ensuring having a correct linkage in some basic cases.
