/**
* Command-line tool that copies the contents of one TileSource
* to another. All arguments are Config name/value pairs, so you need
* to look in the header file for each driver's Options structure for
* options :)
*
* Example: copy a GDAL file to an MBTiles repo:
*
* osgearth_conv
* --in driver gdal
* --in url world.tif
* --out driver mbtiles
* --out filename world.db
*
* The "in" properties come from the GDALOptions getConfig method. The
* "out" properties come from the MBTilesOptions getConfig method.
*
* Other arguments:
*
* --elevation : convert as elevation data (instead of image data)
* --profile [profile] : reproject to the target profile, e.g. "wgs84"
* --min-level [int] : min level of detail to copy
* --max-level [int] : max level of detail to copy
* --threads [n] : threads to use (may crash. Careful.)
*
* --extents [minLat] [minLong] [maxLat] [maxLong] : Lat/Long extends to copy (*)
*
* Of course, the output driver must support writing (by implementing
* the ReadWriteTileSource interface).
