+Use the executable @file{qemu-system-avr} to emulates a AVR 8 bit based machine
+having one for the following cores: avr1, avr2, avr25, avr3, avr31, avr35,
avr4,
+avr5, avr51, avr6, avrtiny, xmega2, xmega3, xmega4, xmega5, xmega6 and xmega7.
+
+As for now it supports few Arduino boards for educational and testing purposes.
+These boards use a ATmega controller, which model is limited to USART & 16 bit
+timer devices, enought to run FreeRTOS based applications (like this
@url{https://github.com/seharris/qemu-avr-tests/blob/master/free-rtos/Demo/AVR_ATMega2560_GCC/demo.elf,,demo})
+
+Following are examples of possible usages, assuming program.elf is compiled for
+AVR cpu
+@itemize
+
+@item Continuous non interrupted execution
+@example
+qemu-system-avr -kernel program.elf
+@end example
+
+@item Continuous non interrupted execution with serial output into telnet
window
+@example
+qemu-system-avr -kernel program.elf -serial tcp::5678,server,nowait -nographic

+and then in another shell
