+    (description
+     "SystemTap provides infrastructure to simplify the
+gathering of information about the running Linux system.  This assists
+diagnosis of a performance or functional problem.  SystemTap eliminates the
+need for the developer to go through the tedious and disruptive
+instrument, recompile, install, and reboot sequence that may be otherwise
+required to collect data.
+
+SystemTap provides a simple command line interface and scripting language for
+writing instrumentation for a live running kernel plus user-space applications.
+We are publishing samples, as well as enlarging the internal \"tapset\" script
+library to aid reuse and abstraction.  SystemTap is a tool for complex
+tasks that may require live analysis, programmable on-line response, and
+whole-system symbolic access, and can also handle simple tracing jobs.")
