+LeakTracer is a small tool for checking a C++ program for memory leaks.
+
+To use LeakTracer, run your program using the provided LeakCheck script.  It
+uses the LD_PRELOAD feature to "overlay" some functions on top of your
+functions (no recompile needed).
+
+LeakTracer uses gdb to print out the exact line where the memory was allocated
+and not freed -- this of course means you have to free all dynamically
+allocated data.  LeakTracer also overrides the global operator new and operator
+delete -- this will give problems if you override them as well.
+
+LeakTracer traces only new/new[] and delete calls -- it does not look at
+malloc/free/realloc.
