/**
|
||
|
|
* A very simple example of using the `icecast.get()` function, which parallels
|
||
|
|
* node's core `http.get()` function. The main difference is that this client
|
||
|
|
* works as expected with servers that respond with the "ICY" http version.
|
||
|
|
*
|
||
|
|
* The `icecast.Client` class also ensures that the "Icy-MetaData" header gets
|
||
|
|
* sent, and the "res" object in the response callback also emits "metadata"
|
||
|
|
* events.
