# Variables:
#  - LINUX_DIST:	Will be used to set some dist-specific presets.
#			Valid values: fedora
#  - LINUX_DIST_VER:	Use depends upon the dist-specific presets.
#			Valid values for "fedora": all version numbers
#				e.g. 3 for fedora core 3, 4 for fedora core 4
#				This is used to set MASTER_SITE_{,SRC_}SUBDIR
#				if it isn't already set.
#  - MASTER_SITE_SRC_SUBDIR:	The subdir for the src RPM's.
#  - DISTFILES:		For simple cases this will be set automatically
#			based upon the DISTNAME.
#  - SRC_DISTFILES:	Variable which contains the corresponding src RPM's.
#			If there's no corresponding src RPM, it has to be
#			set to the empty value (SRC_DISTFILES=	"").
#  - AUTOMATIC_PLIST:	Generate a dynamic plist (please have a look at the
#			porters handbook section which talks about plists.
#			This feature is reserved for rare cases).
#  - BRANDELF_DIRS:	A list of directories with executables to brand
#			as a linux executable. The directories has to not
#			contain libraries.
#  - BRANDELF_FILES:	A list of files to brand as a linux executable in
#			case BRANDELF_DIRS can't be used.
