2 * QR Code generator test worker (TypeScript)
3 *
4 * This program reads data and encoding parameters from standard input and writes
5 * QR Code bitmaps to standard output. The I/O format is one integer per line.
6 * Run with no command line arguments. The program is intended for automated
7 * batch testing of end-to-end functionality of this QR Code generator library.
