Description     : An addon for Trackman by Armin Krausse that saves the
		  Track Records and Setups for each track into a data 
		  file and exports them back into F1GSTATE.SAV when
		  Trackman patches a new configuration.

Other works     : Wistow Superdrome (Oval Track)
		  GP2 Checksummer for DOS
		  CREC Track Records Changer for DOS

Thanks to       : Armin Krausse {akrausse@ix.urz.uni-heidelberg.de} for 
		  trackmanager and his help along the way. 
		  Robert Kimber {kimber@metronet.de} for the checksum 
		  formula.

* Installation *

Ensure that you have Trackman v1.51 or higher up and running on your 
system. The latest version of Trackman can be found at Armin Krausse's
Trackman Homepage:
http://www.geocities.com/MotorCity/Speedway/7479/

Copy TRKCHG.EXE into your Trackman directory.
The first time you run TRKCHG, there will be two data files created.
These data files will be named RECORDS.DAT and SETUPS.DAT.
The RECORDS.DAT file will hold the Track Records for each circuit at
each slot (1-16).  The SETUPS.DAT file will hold the Car Setups for
each circuit, the same setup will be used for each slot. The last
setup saved (any slot) will be the one saved to the SETUPS.DAT file.
If you are already running Trackman v1.51 or higher the data found
in the C?STATE.SAV files will be exported to the RECORDS.DAT and
SETUPS.DAT files for the first time that TRKCHG is run only. (It is
not neccessary after the first time as TRKCHG takes over and adds to
the function of the C?STATE.SAV files. The C?STATE.SAV files will
continue to exist however as TRACKMAN still uses them.)
If Armin changes the name of the Trackman executable in any future
version, you will need to rename the executable to TRACKMAN.EXE.


* Usage *

Simply run TRKCHG from within your Trackman directory.
Note that any parameters that you wish to pass to TRACKMAN can be 
passed to it simply by adding them as parameters of TRKCHG.
You must run TRKCHG rather than TRACKMAN each time. 
TRKCHG will launch TRACKMAN after updating the data files and will
also patch the F1GSTATE.SAV file with the data from the data files
after running TRACKMAN.

You can overcome inadvertantly running TRACKMAN without TRKCHG by 
adding the following code to your AUTOEXEC.BAT :

DOSKEY TRACKMAN = TRKCHG $*

If you wish to force the running of TRACKMAN without TRKCHG you can 
still do so by typing TRACKMAN.EXE instead of simply TRACKMAN.

Note that under DOS the DOS directory must in the path for this to
work. Under Windows 95 the COMMAND subdirectory of your Windows 95
directory must be in the path. The alternative in both cases is to
specify the full path to the DOSKEY util.
