#!/usr/bin/env ruby
#
# A helper script that reads filesystem tags from images in the current directory. If they're tagged with
# TAG_YES or TAG_MAYBE, then the similarly-named JPEG is copied into a "images_for_gallery" directory.
# Then, the "sigal" gallery generator is run (using the config file in ~/.dotfiles) to output the
# gallery into a "html_gallery" directory. Finally, the images_for_gallery directory is removed.
