How can I use GDAL to convert a TIFF displayed in ArcMap using a standard 
deviation stretch of 2 to a TIFF (or other format) I can display using 
Mapserver/OpenLayers?  I can use the raster Export function in ArcMap, but I 
have about 100 TIFFs in 50 .mxds so I'd like to process all the TIFFs using a 
batch file.  I did find a -stddev option in the gdalenhance utility, but it 
gives an error that it's not recognized (using version 1.7.2)  

I also looked for an option in Mapserver to pass the std dev value to the GDAL 
driver before rendering, but I haven't found one.

I'm new working with rasters, so hopefully this makes sense.
