DOC_CONTENTS="
	If you intend for os-prober to detect versions of Windows installed on
	NTFS-formatted partitions, your system must be capable of reading the
	NTFS filesystem. One way to do this is by installing sys-fs/ntfs3g.

	NOTE: Since sys-boot/grub-2.06-rc1, grub-mkconfig disables os-prober by default.
	To enable it, add GRUB_DISABLE_OS_PROBER=false to /etc/default/grub.
