| * QR Code generator test worker (Java) |
| * |
| * 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. |
