// The <shout/shout.h> header is NOT part of the shoutcast server, but part of

// run the icecast server from the same machine, also download the "icecast"
// package from the same location, and install.
// The "libshout" package provides the <shout/shout.h> header, and is the part of
// the mechanism for sending data to the icecast server itself.
//
// The icecast libshout library is under the Lesser GPL license, so before
// using the SndKit with this facility enabled, please ensure that you
// understand the implications of this. The license statement can be found
