-# we use two mechanisms to speed up rebuilds:
-# - older_than: run a command if the output is older than any of the inputs
-# - update: if a command is quick to run, always run it but update the result only on any change
-#
-# avoid combining both mechanisms to generate a single file
-# otherwise you'll see spurious messages about files being updated
-# risk: a file may unnecessarily update without changes, causing unnecessary work downstream
