+	help
+	  ktap is a script-based dynamic tracing tool for Linux
+
+	  It uses a scripting language and lets users trace the Linux
+	  kernel dynamically. ktap is designed to give operational
+	  insights with interoperability that allows users to tune,
+	  troubleshoot and extend kernel and application.
+	  It's similar to Linux Systemtap and Solaris Dtrace.
+
+	  ktap doesn't support kernels older than 3.1.
+
+	  To be able to resolve symbols in DSO and for sdt, you need to
+	  enable elfutils.
+
+	  Your kernel must have CONFIG_EVENT_TRACING,
+	  CONFIG_PERF_EVENTS, and CONFIG_DEBUG_FS enabled to compile.
+
+	  Buildroot automatically enables these in the kernel
+	  configuration.
