"""
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',
			source = 'test.S',
			target = 'asmtest')
