 'd' should have been 'f'. Sorry, I already found this when got v0.1.1
 and forgot to write you. :-) 
Thanks! New version is up at 
http://ccrma.stanford.edu/~kjetil/src/
0.2.0 -> 0.2.1:
  * Removed optional -f argument (that didn't work anyway) for setting the
    filename. Usage for program is now:
    "jack_capture [ -b bitdepth ] [-c channels] [ -B bufsize ] [filename]"
    Thanks to Cesare Marilungo for pointing out the bug.
  * Sound filename is also printed to the screen.
