#Using this client, one can manipulate and query stickers. The script is essentially a raw interface to the MPD protocol's sticker command, and is used in exactly the same way.
#Examples

## set sticker "foo" to "bar" on "dir/song.mp3"
#sticker.py set dir/song.mp3 foo bar
#
## get sticker "foo" on "dir/song.mp3"
#sticker.py get dir/song.mp3 foo
#
## list all stickers on "dir/song.mp3"
#sticker.py list dir/song.mp3
#
## find all files with sticker "foo" in "dir"
#sticker.py find dir foo
#
## find all files with sticker "foo"
#sticker.py find / foo
#
## delete sticker "foo" from "dir/song.mp3"
#sticker.py delete dir/song.mp3 foo
#
#sticker.py
