-
-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.
