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

	   $ ln -s aplay axfer
	   $ ln -s arecord axfer

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

       performs transfer subcommand.
