I have alsaplayer debian package which I use to usual play music.
I have alsaplayer in /usr/local/bin/alsaplayer which I use to develop.
When I want to listen music I type smth like 'alsaplayer-interface'.
BUT. When I wnat to try to run 'unstable' version
I type '/usr/local/bin/alsaplayer-interface'. Last way is not working for
me at first. And at second I can't run script with
'#!/usr/local/bin/alsaplayer-interface' as header coz kernel need full path
to of cmd after '#!'. You can say that I can use
'/usr/bin/env alsaplayer-interface'...
