COMPATIBILITY TO APLAY

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

74
75   A string to which arg[0] points
76       When  args[0]  in  run time points to string ended with 'aplay', it has
77       the same meaning of playback direction. When it points to string  ended
78       with 'arecord', it has the same meaning of capture direction.
