# Travis CI doesn't take symlink changes (or creation!) into

# usually handled automatically (obviously) because we installed
# python. But if we make changes *just* to symlink locations above,
# nothing happens. So for every symlink, write a file...with identical contents,
# so that we don't get *spurious* caching. (Travis doesn't check for mod times,
# just contents, so echoing each time doesn't cause it to re-cache.)
# Overwrite an existing alias.
# For whatever reason, ln -sf on Travis works fine for the ALIAS,
# but fails for the DIR_ALIAS. No clue why. So we delete an existing one of those
# manually.
