-Enable precompiled C++ header support (currently only clang++ and g++ are supported)
-
-To use this tool, wscript should look like:
-
-	def options(opt):
-		opt.load('pch')
-		# This will add `--with-pch` configure option.
-		# Unless --with-pch during configure stage specified, the precompiled header support is disabled
-
-	def configure(conf):
-		conf.load('pch')
-		# this will set conf.env.WITH_PCH if --with-pch is specified and the supported compiler is used
-		# Unless conf.env.WITH_PCH is set, the precompiled header support is disabled
-
-	def build(bld):
-		bld(features='cxx pch',
-			target='precompiled-headers',
-			name='precompiled-headers',
-			headers='a.h b.h c.h', # headers to pre-compile into `precompiled-headers`
-
-			# Other parameters to compile precompiled headers
-			# includes=...,
-			# export_includes=...,
-			# use=...,
-			# ...
-
-			# Exported parameters will be propagated even if precompiled headers are disabled
-		)
-
-		bld(
-			target='test',
-			features='cxx cxxprogram',
-			source='a.cpp b.cpp d.cpp main.cpp',
-			use='precompiled-headers',
-		)
-
-		# or
-
-		bld(
-			target='test',
-			features='pch cxx cxxprogram',
-			source='a.cpp b.cpp d.cpp main.cpp',
-			headers='a.h b.h c.h',
-		)
-
-Note that precompiled header must have multiple inclusion guards.  If the guards are missing, any benefit of precompiled header will be voided and compilation may fail in some cases.
