" summary

An actual Ruby wrapper sends declarative models to a C++ constraint solver (jcode) and demonstrates working examples rather than promises. Example code uses integer_var matrix 9x9 domain 1..9, enforces row/column/block distinct constraints and models problems like Sudoku and Minesweeper. The library is usable from Ruby, hosted on RubyForge, supports most modeling features, and passes models to the solver rather than reimplementing solving; development notes list missing syntactic conveniences but no correctness failures are reported.
