+Assembly support, used by tools such as gas and nasm
+
+To declare targets using assembly::
+
+	def configure(conf):
+		conf.load('gcc gas')
+
+	def build(bld):
+		bld(
+			features='c cstlib asm',
+			source = 'test.S',
+			target = 'asmtest')
+
+		bld(
+			features='asm asmprogram',
+			source = 'test.S',
+			target = 'asmtest')
+
+Support for pure asm programs and libraries should also work::
+
+	def configure(conf):
+		conf.load('nasm')
+		conf.find_program('ld', 'ASLINK')
+
+	def build(bld):
+		bld(
+			features='asm asmprogram',
