This is the "Arc Consistency Crossword Compiler", or arccc. To run the program: arccc The grid file is a block of . # or letters. For example, a 3x3 grid with the top-right and bottom-left squares filled, and an 'a' in the center blank is given by: ..# .a. #.. The grid parser is currently not very robust. Do not add any blank lines nor spaces to the file. The dictionary is just a list of words. Currently, if a word starts with an uppercase letter, it is not used in filling the grid. Currently, the program prints out a working fill when it encounters one, but continues generating fills until killed or exhausting all possibilities.
