COMPATIBILITY TO APLAY

61       The axfer is designed to be compatible to aplay(1) as much as possible.
62       In command line, executions of aplay/arecord  files  under  $PATH  runs
63       axfer  with compatibility mode if filesystem has symbolic link from the
64       aplay/arecord to axfer.

70   A string to which arg[0] points
71       When args[0] in run time points to string ended with  'aplay',  it  has
72       the  same meaning of playback direction. When it points to string ended
73       with 'arecord', it has the same meaning of capture direction.
