+ The FLAC source code has several small example programs that demonstrate how to use the libraries. The source is available on the <a href="download.html">download page</a>, or can be <a href="http://sourceforge.net/cvs/?group_id=13478">checked out from CVS</a> or <a href="http://flac.cvs.sourceforge.net/flac/flac/examples/">browsed online</a>. The examples complement the <a href="api/index.html">API documentation</a>.<br />
+ <br />
+ Currently the examples show how to encode WAV files to FLAC and vice-versa using both libFLAC and libFLAC++. Over time we'll be adding more examples.
