- materialize_emoji_images is a tool that adds symlinks to an existing set of images to add aliases with names that match some of those that get are built into the ligature table. This is for the convenience of folks who want to review the images and see what sequences/codepoints we support. I've been asked to do this enough that I might as well just build a tool for it. - flag_info picks out the flag images in a directory based on two kinds of naming styles the data use (ASCII or emoji_u+codepoint) and presents them in a list similar to that in the Makefile. It helps when tracking down what flags we support and what we don't by making it easier to compare sets of flag images with different naming. This is another quick one-off.
