REM drivercab.cmd
REM

REM this script will generate a driver.cab for each sku appropriate to this
REM language. the files to be used are contained in drvindex.inf for each
REM sku, which is read by cddata.cmd, and passed through txt files here.

REM details:
REM we are passed .txt lists for each sku, and then a file called
REM commondrivers.txt for all common files. if the commondrivers.txt file
REM exists, we can assume that we are not in incremental mode, as the idea
REM of a common cab doesn't really make sense in an incremental environment.
REM
REM if commondrivers.txt does not exist, we will use cabinc.exe to add
REM the changed files in each SKU to the appropriate driver.cab
REM
REM if perdrivers.txt does not exist, then there are no changes for per or
REM alternately the per cab is equivalent to the common cab if not in
REM incremental mode.
