echo To make a TradeWars 2002 NG file for a particular game use:
echo           TW2TOOLS gamename logextension
echo If you are just starting, choose a gamename that is up to 7
echo characters long.
echo ú
echo Then you will need to capture each TW2002 session to a disk file.
echo You may want to name your logs based on dates, or you can simply
echo name each one gamename.LOG.  Then run this TW2TOOLS batch file after
echo each session.
echo ú
echo If you want to keep multiple logs, you can use the optional logextension.
echo For example:
echo           TW2TOOLS RACER 924
echo would analyze the log named RACER.924, add the results into the
echo accumulated knowledge in files named RACER.NUM, RACER.RTE and make a
echo Norton Guides file named RACER.NG.
