+//     - This is the highest priority backend on Linux (higher priority than ALSA) since it is commonly
+//       installed by default on many of the popular distros and offer's more seamless integration on

 //   - Remove dependency on asound.h for the ALSA backend. This means the ALSA development packages are no
 //     longer required to build mini_al.
