[gdal-dev] gdal_translate syntax input separate R, G, B output combined RGB

[Greg Coats]

I have 3 single band GeoTIF images of the same geographic area: one  
for the Red band, one for the Green band, and one for the Blue band,  
gtif_R.tif, gtif_G.tif, gtif_B.tif.  Please, what is the  
gdal_translate syntax http://www.gdal.org/gdal_translate.html to  
combine these 3 single band GeoTIF images into 1 three band RGB  
GeoTIF image, gtif_RGB.tif?
