pub const ENV_LANGUAGE: &str = "DEV_PRUNE_LANG";Expand description
Environment variable that overrides the language setting for one invocation.
What a script or a CI job sets when it wants output in a known language whatever the
machine is configured for. An unrecognised code falls back to DEFAULT_LANGUAGE
rather than failing, because this is read before the command runs and a typo in a
cosmetic setting should not stop a prune.
