Use Format in Log

If this item is ticked, then before typesetting foo.tex will look in foo.log to see which format should be used. (In log files created by the format appears after the `` &'' on line 2.) If the log file exists and the format is known (i.e., exactly matches one of the formats at the bottom of the TEX menu) then automatically changes the current format if necessary. If the log file does not exist or does not contain a known format then the current format will be used. The state of ``Use Format in Log'' is remembered when you quit . Note that if you manage to create a log file with a known but incorrect format then you'll have to turn off ``Use Format in Log'' and manually select the correct format before typesetting the corresponding input file.
