# $(POUND_SIGN) is just a #.  Used to turn a feature off.
# The $(POUND_SIGN)POUND_SIGN:sh construct is just so make doesn't have to
# spawn a shell and redefine POUND_SIGN if it is already defined (e.g.
# $(SRC)/Makefile.master was already included).
$(POUND_SIGN)POUND_SIGN:sh = echo '\043'


#
# Optional features (set to $(POUND_SIGN) to turn off):
#
# OPTION_UTILS:
#	Build the userland utilities.
#	NOTE: these utilities will be installed in
#	      /platform/$(PLATFORM)/boot/grub, not /boot/grub.
#
# OPTION_DOCS:
#	Build and install some GRUB documentations, e.g. man and info files.
#	NOTE: these docs will be installed in
#	      /platform/$(PLATFORM)/boot/grub, not /boot/grub.
#
# OPTION_FS:
#	Build additional filesystem support into GRUB. This will increase
#	the sizes of stage2 and pxegrub and may cause malfunction.
#
# STAGE2_NETBOOT:
#	Include netboot support in stage2 (on by default).
#	This only affects stage2, not pxegrub (diskless support).
