/*
 * This script makes use of the AtdfService class to convert Microchip ATDF files to Bloom's TDF format.
 *
 * Upon conversion, the script will also run validation on the newly generated TDFs, and output any failures.
 * Validation failures will *not* prevent the saving of the newly generated TDFs.
 *
 * Usage:
 *   To convert a single ATDF file, located at [PATH_TO_ATDF], and store the generated TDF in [OUTPUT_DIR_PATH]:
 *     php ./ConvertAtdfToTdf.php [PATH_TO_ATDF].atdf [OUTPUT_DIR_PATH]
 *
 *   To convert all ATDF files located in [PATH_TO_ATDF_DIR] (recursive search), and store the generated TDF files
 *   in [OUTPUT_DIR_PATH]:
 *     php ./ConvertAtdfToTdf.php [PATH_TO_ATDF_DIR] [OUTPUT_DIR_PATH]
 *
 * As mentioned in the AtdfService, this script is only intended for first-passes. It will do most of the work, but the
 * newly generated TDFs may require some manual touch-ups. This is why we run them through validation.
