%description
GNU GRUB is a Multiboot boot loader. 
It was derived from GRUB, GRand Unified Bootloader, which was 
originally designed and implemented by Erich Stefan Boleyn. 

Briefly, bootloader is the first software program that runs when
a computer starts. It is responsible for loading and transferring
control to the operating system kernel software (such as the Hurd
or the Linux). The kernel, in turn, initializes the rest of the 
operating system (usually GNU). 

%description -l ja
GNU GRUB はマルチブートローダです。
この名前は GRand Unified Bootloader (壮大な 統一されたブート
ローダ) に由来し、元来は Erich Stefan Boleyn によって、設計・
実装されたものです。

手短に言えば、ブートローダとはコンピュータが起動する際に最初
に実行されるプログラムで、(Hurd や Linux のような) オペレー
ティングシステムのカーネルをディスクから読み込んで制御を渡す
作業を担当します。カーネルは、それを受けて、オペレーティング
システムの他の部分 (通常は GNU) を初期化します。
