-# Check that the desired version of rustfmt is installed.

-# Rustfmt is still immature enough that its formatting decisions can change

-# To work around this, we only verify formatting when a specific version of
-# rustfmt is installed.

-# Exits 0 if the right version of rustfmt is installed, 1 otherwise.

-# With the --install option, also tries to install the right version.
