+         Saying Y here includes support for reading Squashfs file systems

+         aimed at embedded systems with slower CPUs where the overheads
+         of zlib are too high.
+
+         LZ4 is not the standard compression used in Squashfs and so most
+         file systems will be readable without selecting this option.
