	# We make use of the rebuild.config file, so please make sure that your
	# settings are correct there!
	# We also assume that your drush aliases are setup correctly for
	# @mysite.dev and @mysite_d5.prod. Please check mysite.aliases.drushrc.example,
	# make sure your @mysite.dev alias is set up correctly, rename the file
	# to mysite.aliases.drushrc.php and move it into your ~/.drush directory.
