+	  The uftrace tool is to trace and analyze execution of a
+	  program written in C/C++. It was heavily inspired by the
+	  ftrace framework of the Linux kernel (especially function
+	  graph tracer) and supports userspace programs.
+	  It supports various kind of commands and filters to help
+	  analysis of the program execution and performance.
