 KCachegrind is a visualisation tool for the profiling data generated
 by calltree, a profiling skin for valgrind. Applications can be
 profiled using calltree without being recompiled, and shared libraries
 and plugin architectures are supported.

 For visualising the output from other profiling tools, several converters
 can be found in the kcachegrind-converters package.
