+Memleax debugs memory leaks of running processes by attaching to them,
+without recompiling or restarting. It hooks the target process's invocation
+of memory allocation and free and reports the memory blocks which live
+long enough as memory leak, in real time. 
+
+It is convenient to use, and suitable for production environments.
+There is no need to recompile the program or restart the target process.
+You can run memleax to monitor the target process, wait for the real-time
+memory leak report, and then kill it with ctrl-c to stop monitoring.
