 * We provide a standard set of profiles for each codec - these are defined

 * your profiles using WMACT_LOAD_PROFILE, or you can override them by
 * declaring a profile with the same name.
 * 
 * There is more documentation on the profiles and actions which are available
 * in WMProfiles.h, and in the documentation WAS-0008 Using the Wolfson Device
 * Control Library, provided in the docs directory of the kit.
 * 
 * The tool MakeProfile.exe, provided in the Apps directory of the kit, can
 * take one or more files from the evaluation board software and convert
 * them into a form suitable for this file.
