    (description
     "Sysprof performs detailed, accurate, and fast CPU profiling of an entire
GNU/Linux system including the kernel and all user-space applications.  This
helps find the function(s) in which a program spends most of its time.

It uses the kernel's built-in @code{ptrace} feature and handles shared
libraries.  Applications do not need to be recompiled--or even restarted.")
