.SH COMPATIBILITY TO APLAY
|
|
|
|
|
|
|
|
|
|
The
|
|
|
|
|
.I 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.
