17#
18# Simulator of the PyUIPC module.
19#
20# This is a simulation of the PyUIPC module emulating offsets that are needed
21# by the logger.
22#
23# This module can also be run as a program, in which case it connects to an
24# already running logger (that uses this module in place of the real pyuipc),
25# and various commands can be given to query or modify the values of the
26# offsets. There is a 'help' command and completion also works.
27#
28# This module is used instead of the real PyUIPC module, if the program is not
29# running on Windows or the FORCE_PYUIPC_SIM environment variable is present.
