run_ices, a script to start ices2 from the command line.
Usage: $0 [OPTION] mountpoint [-o filename] ...
Example: $0 -S localhost -P 8000 -p hackme -b 64000 path/low.ogg
		-o low.ogg -b 128000 path/high.ogg -o high.ogg

General configuration:
  -sr n		Set sample rate of audio device [$samplerate]
  -c n		Set number of channels [$channels]
  -m module	Use named ices module (oss,sun) [$module]
  -S server	Server to stream to [$server]
  -P port	Port to connect to [$port]
  -p pass	Server password
  -A title	Artist for encoding
  -T title	Title for encoding
  -t n		Finish encoding after n seconds [don't stop]

Per-instance encoding configuration:
  -b n		Set bitrate [$bitrate]
  -o filename	Spawn a wget process to write this encoding to file

When listing more than one mountpoint, you only need to override the
parameters that need changing since the last one.  Multiple encodings
come at the expense of CPU.  If you use -o, always specify it AFTER the
mountpoint, and make sure you have the GNU wget application installed.
