upstream is a simple command-line utility for streaming audio to a Shoutcast/Icecast server.
upstream depends on libshout and
taglib.
Assuming those are installed, build the upstream binary by typing make.
To install, copy the upstream binary to your personal bin directory.
Stream a bunch of MP3 files:
$ upstream --host example.org *.mp3
Stream OGG files from standard input:
$ cat *.ogg | upstream --ogg -
