# "makeinfo --info" MUST be able to read PNGs from CWD for info images
# to work, hence $(INFO_IMAGES_DIR) -> $(outdir)/ symlink.
# $(outdir)/$(INFO_IMAGES_DIR)/*.png symlinks are only needed to view
# out-www/*.info with Emacs -- HTML docs no longer need these
# symlinks, see replace_symlinks_urls in
# buildscripts/add_html_footer.py.

# make dereferences symlinks, and $(INFO_IMAGES_DIR) is a symlink
# to $(outdir), so we can't use directly $(INFO_IMAGES_DIR) as a
# prerequisite, otherwise %.info are always outdated (because older
# than $(outdir), hence this .dep file
