"""Python bindings to the Nectarine Queue interface
|
|
|
|
If used as a script, print on stdout the current track song and artist(s).
|
|
|
|
It's mainly useful if you work with terminals around and don't want to keep the
|
|
Nectarine tab under your eyes all the time (even if it's raina's design).
|
|
Respect their servers, and long live Nectarine!

Requirements: the requests package.
