# \brief Example for debugging a service
# \author Norman Feske
# \date 2011-09-13
#
# This example shows how GDB monitor can be used to debug a Genode service.
# GDB monitor sits in between the service and the service's parent. Any
# service announcements are transparently propagated through the GDB
# monitor to the parent. This way, the internal state of a service can
# be observed at any time via a remote GDB connection. In the example,
# the remote GDB connection is realized via an UART device. Alternatively,
# 'tcp_terminal' could be used (to attach GDB via a network connection).
