# We don't want to have to generate new rules for every single asset, so we find

# (`PUBLIC_ASSETS`). The `%` wildcard works like it does in `public/%` below.

# wildcard rule: % on the left-hand side will be matched and replaced on the
# right-hand side. So `public/index.html` depends on `styleguide-app/index.html`
#
# - automatic variables: `$@` is the target (left-hand side of the rule.) `$<`
#   is the first dependency.
# - about the leading `@` in `mkdir`: leading `@` turns off echoing the
#   command. We're just reducing log spam here.
# - about `$(@D)`: $@ gets the target (left-hand side of the rule). Any
#   automatic variable plus `D` gets the directory of that file, so `$(@D)` is
#   the target's directory.
