+There is also a command-line tool to get ASCII reports from data files without
+the need to use KCachegrind.
+
+The format of Callgrind output is documented.  With conversion scripts,
+KCachegrind is able to visualize output of other profilers like OProfile, a
+system-wide profiler for Linux using statistical sampling with hardware
+performance counters.  There also exist converters for profiling output of
+Python, PHP, and Perl.")
