- Support --ignore_missing flag to skip missing data on output. When all_images is set, this skips sequences for which we have no image files. When all_images is not set, this skips sequences for which we have image files but are not in the canonical sequence list (e.g. older sequences for which we included skin tone variants but which later versions of unicode decided there shouldn't be). - Use alias information to add alias sequences when not using all_images and we have an image for the target sequence. - Use alias information to mark missing images with '-alias-' when we expect an alias (note, not only when we actually have one) - Embed tool name, date, and arguments in a comment in the generated html.
