- * QR Code generator test worker
- * 
- * This program reads data and encoding parameters from standard input and writes
- * QR Code bitmaps to standard output. The I/O format is one integer per line.
- * Run with no command line arguments. The program is intended for automated
- * batch testing of end-to-end functionality of this QR Code generator library.
