+TMON - A Monitoring and Testing Tool for Linux kernel thermal subsystem
+
+Why TMON?
+==========
+Increasingly, Linux is running on thermally constrained devices. The simple
+thermal relationship between processor and fan has become past for modern
+computers.
+
+As hardware vendors cope with the thermal constraints on their products, more
+and more sensors are added, new cooling capabilities are introduced. The
+complexity of the thermal relationship can grow exponentially among cooling
+devices, zones, sensors, and trip points. They can also change dynamically.
+
+To expose such relationship to the userspace, Linux generic thermal layer
+introduced sysfs entry at /sys/class/thermal with a matrix of symbolic
+links, trip point bindings, and device instances. To traverse such
+matrix by hand is not a trivial task. Testing is also difficult in that
+thermal conditions are often exception cases that hard to reach in
+normal operations.
+
+TMON is conceived as a tool to help visualize, tune, and test the
+complex thermal subsystem.
+
+Files
+=====
+	tmon.c : main function for set up and configurations.
+	tui.c : handles ncurses based user interface
+	sysfs.c : access to the generic thermal sysfs
+	pid.c : a proportional-integral-derivative (PID) controller
+	that can be used for thermal relationship training.
+
+Requirements
+============
+Depends on ncurses
+
+Build
+=========
+$ make
+$ sudo ./tmon -h
+Usage: tmon [OPTION...]
+  -c, --control         cooling device in control
+  -d, --daemon          run as daemon, no TUI
+  -l, --log             log data to /var/tmp/tmon.log
+  -h, --help            show this help message
+  -t, --time-interval   set time interval for sampling
+  -v, --version         show version
+  -g, --debug           debug message in syslog
+
+1. For monitoring only:
+$ sudo ./tmon
