// Simple command-line tool for building wave banks from 1 or more .WAV files. This
// generates binary wave banks compliant with XACT 3's Wave Bank .XWB format. The
// .WAV files are not format converted or compressed.
//
// For a more full-featured builder, see XACT 3 and the XACTBLD tool in the legacy
// DirectX SDK (June 2010) release.
