I was thinking to have the following:

bseek=BYTES     skip BYTES bytes at start of output\n\
bskip=BYTES     skip BYTES bytes at start of input\n\
obseek=M[,N]    skip M bytes at start of each output block and N bytes after
ibskip=M[,N]    skip M bytes at start of each input block and N bytes after

I found the *tail names too long for day-to-day usage. Perhaps if we could 
find a shorter name, I could drop the second numeric argument in favour of 
a separate option.

Well, I am in the process of writing some proof-of-concept code right 
now. As for the documentation...ehmm...ummm...emm... :-)
