 Sysprof is a sampling CPU profiler that uses a ptrace in Linux kernel to
 profile the entire system, not just a single application. Sysprof handles
 shared libraries and applications do not need to be recompiled. In fact they
 don't even have to be restarted.
 .
 This package provides the development files for the user interface shared
 library.
