- * When zlib is unavailable, we should still be able to validate
- * uncompressed zip archives.  That requires us to be able to compute
- * the CRC32 check value.  This is a drop-in compatible replacement
- * for crc32() from zlib.  It's slower than the zlib implementation,
- * but still pretty fast: This runs about 300MB/s on my 3GHz P4
- * compared to about 800MB/s for the zlib implementation.
