     "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.")
