#@desc <h3>Launch with <tt>qemu</tt> and connect with <tt>gdb</tt></h3>
#@desc <p>This will launch the target on the local machine using <tt>qemu</tt>. Then in a second
#@desc terminal, it will connect <tt>gdb</tt> to QEMU's GDBstub.
#@desc GDB must already be installed on your system, it must support your target architecture
#@desc (you may install <tt>gdb-multiarch</tt>), and it must embed the Python 3 interpreter. You
#@desc will also need <tt>protobuf</tt> installed for Python 3.
