Is there any way of merging two sets of tiles with gdal2tiles?

[المشرف العام]

I've executed gdal2tiles against 2 raster coverages:

• One big raster coverage, composed by several TIFF files. Example of tile: http://dl.dropbox.com/u/6599273/319.png
• One single TIFF file, geographically placed inside the coverage above, but that wasn't procesed in the previous step. Example of tile: http://dl.dropbox.com/u/6599273/319_bis.png

So, I first executed gdal2tiles against a "puzzle" of TIFF files, with a missing piece, and then I executed gdal2tiles against that single missing piece. I want to merge both tiles set. Zoom levels were 4-14, only Google Maps output. Only levels 4-12 have the problem (tiles with the same coords).

Is there any way of merging tiles or should I execute gdal2tiles against the whole "puzzle"?

Thanks in advance, and best regards
