It does not print crc. Inspecting code quickly, it only displays crc
**Warning** if there is mismatch but proceeds after that as if nothing
has happened. So, it was not suitable for the task anyhow.

I think -v option can be added to verify the integrity of archive and
return 0 [OK] or an shell error code so it could be used in a shell
script properly.
