Currently, this directory just contains _example_ code for using KCachegrind's libcore for command line tools. It is not expected to be packaged with KCachegrind (therefore, nothing is installed).
Eventually, it will grow into a convertion/merge/filter tool for profile data, and a replacement for the callgrind_annotate script from the Valgrind package (which is broken as it does not handle profile data with instruction granularity, as well as cycle detection).
