+	  Heaptrack traces all memory allocations and annotates these
+	  events with stack traces. Dedicated analysis tools then allow
+	  you to interpret the heap memory profile to find hotspots,
+	  memory leaks, allocation hotspots and temporary allocations.
+
+	  Zstandard offers better (de)compression performance compared
+	  with gzip/zlib, making heaptrack faster and datafiles smaller,
+	  so enabling BR2_PACKAGE_ZSTD is recommended.
