# Program-to-Weights Compilation

The decision-making part of a Maven-style build tool has been compiled into a fixed weight matrix and used to build ZXing 3.5.3 for real, producing JARs byte-identical to Apache Maven's with all 549 upstream tests passing. The weights come from compiling a program, not from training or gradient descent; the price is speed, with a clean build including tests taking about 1.42 times as long as the same logic in Python.
