I'm not sure I understand what you are asking for, Lars.
The WD tags are all %tagname% and the VWS tags are all ^v..nnn^
WD clientraw.txt has units of measure as C, knots, rain-mm, baro-hPa
VWS WeatherFlash text files have units of measure in F, mph, rain-in, baro-inHg
Did you want VWS to emit a 'clientraw.txt' like file? If so, it already does with WeatherFlash http uploads to your website.
In any event, changing tag names from WD to VWS (or vice versa) will be a manual effort to match variables provided by each program. WD has a lot more %tags% that VWS offers.
Hope this helps...
Best regards,
