# This script allows you to play music using a chorizo (or whatever food you
|
|
# like) keyboard ! See README for more info and links.
|
|
|
|
# As all the other scripts in this repository, I release it under a very
|
|
# permissive license. To make a long story short : do whatever you want with
|
|
# this script (but try to have fun :), I don't mind. It would be cool to quote
|
|
# the origin of the script if you reuse it, but you don't have to. I'd like to
|
|
# be noticed of what you did cool with it (if you think it's worth). :)
|
|
# Ah, I almost forgot : If by chance we ever meet and you think this script is
|
|
# worth, you can buy me a soda :)
