+	help
+	  If this option is set, support for LZ4 compressed images
+	  is included. The LZ4 algorithm can run in-place as long as the
+	  compressed image is loaded to the end of the output buffer, and
+	  trades lower compression ratios for much faster decompression.
+	  
+	  NOTE: This implements the release version of the LZ4 frame
+	  format as generated by default by the 'lz4' command line tool.
+	  This is not the same as the outdated, less efficient legacy
+	  frame format currently (2015) implemented in the Linux kernel
+	  (generated by 'lz4 -l'). The two formats are incompatible.
