SUMMARY = "Multi-purpose linux bootloader"
HOMEPAGE = "http://www.syslinux.org/"
DESCRIPTION = "The Syslinux Project covers lightweight bootloaders for MS-DOS FAT filesystems (SYSLINUX), network booting (PXELINUX), bootable "El Torito" CD-ROMs (ISOLINUX), and Linux ext2/ext3/ext4 or btrfs filesystems (EXTLINUX). The project also includes MEMDISK, a tool to boot legacy operating systems (such as DOS) from nontraditional media; it is usually used in conjunction with PXELINUX and ISOLINUX."
