pangrid, a crossword file format interconversion and publishing tool (the name is a tribute to pandoc). no repo up yet because I need to get approval from work first, but it works nicely for a few text and binary formats, and I'm working on extracting grids from images in PDF files and on webpages to reexport into some interactive format.
