+%description
+This project (originating in Google LevelDB key-value store) collects
+a few CRC32C implementations under an umbrella that dispatches to a
+suitable implementation based on the host computer's hardware
+capabilities.
+
+CRC32C is specified as the CRC that uses the iSCSI polynomial in RFC
+3720. The polynomial was introduced by G. Castagnoli, S. Braeuer and
+M. Herrmann. CRC32C is used in software such as Btrfs, ext4, Ceph and
+leveldb.
+
+%description -l pl.UTF-8
+Ten projekt (wywodzący się z bazy klucz-wartość Google LevelDB) zbiera
+kilka implementacji CRC32C w obudowaniu, które wybiera implementację
+pasującą do możliwości sprzętowych komputera.
+
+Algorytm CRC32C to cykliczny kod nadmiarowy, wykorzystujący wielomian
+iSCSI określony w RFC 3720. Wielomian został wprowadzony przez G.
+Castagnoliego, S. Braeuera i M. Herrmanna. Algorytm jest
+wykorzystywany w takim oprogramowaniu, jak btrfs, ext4, ceph czy
+leveldb.
