This utility is designed to check for the presence, validity, and access 
permissions of the TVStudy terrain, land clutter, and NADCON data.  To use 
it, simply place the files contained in the checkTerrain.zip file in the 
dbase/ directory. Then, change directory into your dbase/ directory, and 
depending on your system, from the command line, run whichever one of 
these commands works:

python checkTerrain.py
python2 checkTerrain.py
python3 checkTerrain.py

Alternatively, once the files are placed in the dbase/ directory, you may 
go to the Help menu and select Check Installation from within TVStudy.

On a test machine, with the optional CDED and NLCD data installed, the 
verification took 15-20 minutes.
