[Thomas:
 - use "config" instead of "menuconfig" in Config.in
 - add missing final newline in Config.in
 - pass DESTDIR=$(TARGET_DIR) only at install time
 - wrap too long lines in the .mk file
 - remove useless empty newline at end of .hash file.]

+	bool "zstd"
+	help
+	  Zstandard, or zstd as short version, is a fast lossless
+	  compression algorithm, targeting real-time compression
+	  scenarios at zlib-level and better compression ratios
+
+	  The selection of other packages will enable some features:
+	  xz, lz4 and/or zlib will enable support for corresponding
+	  compression formats
