		+	Logging Data and Playing It Back
		+
		+	Recording data in CARMEN is made simple with the '''bold'''logger program. When you are ready to start logging data, simply start the logger program with the following command. At the very least, central and must be running.
		+
		+	./logger [filename].log[.gz]
		+
		+	[filename] specifies a filename for the sensor log. If the file already exists, the program will ask to overwrite it. If an answer other than "Y" or "y" is given, then the logger will quit. There is no way for this program to append new data to an old logfile.
		+
		+	The logfile will begin with the following message, which explains the format of the file. After that, the file is simply a list of CARMEN messages in the order they were received.

		+	There is no way to pause recording; to stop simply type "ctrl-C" in the window in which logger is running.
		+
		+	To start a playback of the data, then start the main CARMEN programs normally, except replace base_services or simulator with the program playback as follows:
		+
		+	./playback [filename].log[.gz]
		+
		+	This program will immediately start sending messages from the logfile to central, to be passed to other programs.
		+
		+	To have more control over the playback, running playback_control to call up a graphic user interface, as below.
