 The ''memusagestat'' utility was extracted from the glibc sourcecode. It is capable of creating a graph from a trace recorded by the libmemusage.so.
+{{{
+$ MEMUSAGE_OUTPUT=some.result LD_PRELOAD=/lib/libmemusage.so ./some_application
+$ ./memusagestat -o some.result.png some.result
+}}}
+
+==== Recording paint traces ====
+
+In Qt 4.6 a new graphicssystem called trace was introduced. It allows to record all drawing operations into a trace buffer, store it to disk. Later it can be replayed with the qttracereplay utility of Qt.
+
+{{{
+$ ./my-qt-app -graphicssystem trace
+$ qttracereplay the_trace_file
+}}}
