Although all patches have been merged, below are a few suggestions:

- Please make help working.  It took some time for me until figuring
  out the fact that the direction option is mandatory, for example.

- The input/output from/to a terminal can be checked via isatty().
  That allows us to see garbages by a mistakenly started command.

- A man page.  (I thought Debian mandates it?)


In anyway, thanks for your hard work!
