+	  Set of utilities for testing the real-time behaviour of a
+	  Linux system.
+
+	  All tools are simple C programs with no dependencies, except
+	  the hwlatdetect utility, which is a Python script and
+	  therefore requires the Python interpreter. It will only be
+	  installed if a Python interpreter has been selected in the
+	  Buildroot configuration.
+
+	  Note that this package requires a toolchain built with the
+	  NPTL implementation of the pthread API (this is always the
+	  case with glibc toolchains, but may not necessarily be the
+	  case with uClibc toolchains, since the thread implementation
+	  is configurable).
