#		This is the GHC Makefile for MacOS X-specific targets
#
# Targets: 
#
#	framework-pkg  [MacOS only]
#		Builds /Library/Frameworks/GHC.framework wrapped into a Mac
#		installer package; must be executed in a ./configure'd tree
#		(--prefix doesn't matter as it will be overridden); other
#		./configure arguments are passed through, unless overwritten
#		with XCODE_EXTRA_CONFIGURE_ARGS.  A deployment target can
#		be specified by setting the corresponding ./configure
#		argument or by setting MACOSX_DEPLOYMENT_TARGET.
#
#	framework-binary-dist  [MacOS only]
#		Builds GHC.framework encapsulating a binary distribution
#		(to give a relocatable framework); must be used in a fully
#		built tree
