To run these .bat files, you'd have to
extract dsc.exe from ./src/diamond/dsc_exe.zip 
into a directory of your %PATH%. If you did
fresh cvs-checkout, you only need to run 'regen_db.bat',
which will generate initial (empty) database and index
files.

NOTE:: If you don't have or unable to use dsc.exe on 
your system, extract prebuilt blank database files
from blank_dbs.zip into this directory
