visualisation tool for the Valgrind profiler

 KCachegrind is a visualisation tool for the profiling data generated
 by calltree, a memory profiling tool for valgrind. Any executable can be
 profiled using calltree without being recompiled, including multi-threaded
 applications, shared libraries, and plugins.
 .
 For visualising the output from profiling tools other than Valgrind, several
 converters can be found in the kcachegrind-converters package.
 .
 This package is part of the KDE Software Development Kit module.
