%description
GRUB is a GPLed bootloader intended to unify bootloading across x86
operating systems. In addition to loading the Linux and *BSD kernels,
it implements the Multiboot standard, which allows for flexible
loading of multiple boot images (needed for modular kernels such as
the GNU Hurd).

GRUB 2 is derived from PUPA which was a research project to
investigate the next generation of GRUB. GRUB 2 has been rewritten
from scratch to clean up everything for modularity and portability.

GRUB 2 targets at the following goals:
- Scripting support, such as conditionals, loops, variables and
  functions.
- Graphical interface.
- Dynamic loading of modules in order to extend itself at the run time
  rather than at the build time.
- Portability for various architectures.
- Internationalization. This includes support for non-ASCII character
  code, message catalogs like gettext, fonts, graphics console, and so
  on.
- Real memory management, to make GNU GRUB more extensible.
- Modular, hierarchical, object-oriented framework for file systems,
  files, devices, drives, terminals, commands, partition tables and OS
  loaders.
- Cross-platform installation which allows for installing GRUB from a
  different architecture.
- Rescue mode saves unbootable cases. Stage 1.5 was eliminated.
- Fix design mistakes in GRUB Legacy, which could not be solved for
  backward-compatibility, such as the way of numbering partitions.

%description -l de.UTF-8
GRUB (GRand Unified Boot-loader) ist ein Bootloader, der oft auf
Rechnern eingesetzt wird, auf denen das freie Betriebssystem Linux
läuft. GRUB löst den betagten LILO (Linux-Loader) ab.

GRUB wurde innerhalb des GNU Hurd-Projektes als Boot-Loader entwickelt
und wird unter der GPL vertrieben. Aufgrund seiner höheren
Flexibilität verdrängt GRUB in vielen Linux-Distributionen den
traditionellen Boot-Loader LILO.

%description -l hu.UTF-8
GRUB egy GPL liszenszű rendszerbetöltő. Linux és *BSD kernelek
betöltése mellett támogatja a Multiboot standard-ot, amely lehetővé
teszi boot képek betöltését (moduláris kerneleknek kell, mint pl. a
GNU Hurd).

GRUB2 céljai a következők:
- szkriptelés támogatása, úgymint feltételek, ciklusok, változók,
  függvények.
- grafikus felület
- modulok dinamikus betöltése futási időben
- hordozhatóság több architektúrára
- többnyelvűség: nem-ASCII karakterek támogatása, üzenetkatalógusok,
  mint gettext, betűtípusok, grafikus konzolon, és így tovább
- valós memória kezelés, amellyel még bővíthetőbbé tehetjük
- moduláris, hierarchikus, objektum-orientált keretrendszer
  fájlrendszerekhez, fájlokhoz, eszközökhöz, meghajtókhoz,
  terminálokhoz, parancsokhoz, partíciós táblákhoz és OS betöltőkhöz

Éste es GRUB - Grand Unified Boot Loader - un administrador de
inicialización capaz de entrar en la mayoría de los sistemas
operacionales libres - Linux, FreeBSD, NetBSD, GNU Mach, etc. como
también en la mayoría de los sistemas operacionales comerciales para
PC.

El administrador GRUB puede ser una buena alternativa a LILO, para
usuarios conmás experiencia y que deseen obtener más recursos de su
cargador de inicialización (boot loader).

GRUB jest bootloaderem na licencji GNU, mającym na celu unifikację
procesu bootowania na systemach x86. Potrafi nie tylko ładować jądra
Linuksa i *BSD: posiada również implementacje standardu Multiboot,
który pozwala na elastyczne ładowanie wielu obrazów bootowalnych
(czego wymagają modułowe jądra, takie jak GNU Hurd).
