  83 # This is a bit messy. It regenerates the dependencies on each build so
  84 # that we catch files being added and removed. There are other ways of doing
  85 # this (e.g. per-file dependency files) but that requires more in-depth changes
  86 # to the build system. Compile time is not an issue for us, so the
  87 # rebuild on every make invocation isn't a problem we need to care about. Just
  88 # do it silently so it doesn't make the build unnecessarily noisy.
