You're welcome! FWIW, I've hacked it a bit more so that the checksum file 
is now optional, and stdin is used when no file is given. Also, for input 
formats where the hash algorithm can be determined from, it's used 
according to that. 

For cksum(1) -o[12] and sum(1) those tools/options still need to be 
specified, just like when -n ("normal"?!) is used. I think those should be 
nuked from orbit / merged in consistently.
