%description
The diet libc is a libc that is optimized for small size. It can be
used to create small statically linked binaries for Linux on alpha,
arm, hppa, ia64, i386, mips, s390, sparc, sparc64, ppc and x86_64.

%description -l pl.UTF-8
diet libc to biblioteka libc zoptymalizowana pod kątem rozmiaru.
Może być używana do tworzenia małych, statycznie zlinkowanych
binariów dla Linuksa na architekturach alpha, arm, hppa, ia64, i386,
mips, s390, sparc, sparc64, ppc i x86_64.

%description -l pt_BR.UTF-8
