# Test some remote file I/O.  The associated Python script uses the
# Python API to create and send vFile:* packets to gdbserver to
# perform actions like 'stat'.  The same action is then performed
# directly from Python (e.g. a 'stat' is performed), and the results,
# from gdbserver, and from the local syscall, are compared.
