 * @file compareDigitReaders.C
 * @brief Translate TPC DDL file into an ascii dump
 *
 * Usage:
 * <pre>
 *   aliroot -b -q -l raw2ascii.C'("infile", "outfile", slice, patch, "reader")' | tee compareDigitReaders.log
 * </pre>
 *
 * The macro translates a TPC DDL raw data file into an ascii dump using
 * a small chain with the AliHLTTPCDigitDumpComponent. The only mandatory
 * parameter is the input file.
 *   - outfile might be skipped -> default infile.ascii
 *   - optional parameter 'slice':
 *     can be skipped if infile obeys DDL naming rule
 *   - optional parameter 'patch':
 *     can be skipped if infile obeys DDL naming rule
 *   - optional parameter 'reader': default 'decoder'
 *     packed (AliRawStream), decoder (AliAltroDecoder)
 *
