   What is "where" here? I think it should be 2 parameters -- position
in the file (in bytes) and total file size; the total could be None if
the size is unknown (the tar is piped from network or a (g/bz)zip
subprocess).

   Definitely a good idea!

           Programmers don't die, they just GOSUB without RETURN.
