#Make is actually an interactive configuration step.
#The configuration is highly sensitive to your specific machine.
#Although it is quite good, it will default to accuracy over speed.
#Powertweakers might want to configure interactively (also for cross-compile)
# by uncommenting the next line and commenting the yes ""| make || die line .
#	make || die

#atlas will automatically do a parallel make if possible.	
	yes "" | make || die
