/**
 * 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).
