22 This file provides for an object to source a SHOUTcast (www.shoutcast.com) stream.
23 It uses the lameencdec.h interface (and lame_enc.dll) to encode, and JNetLib to send the data.
26 This object will not auto-reconnect on disconnect. If GetStatus() returns error, the callee needs to
27 delete the object and create a new one.
