-/// [`diff`][mod@diff] is implemented in terms of the [similar] library.
+/// Implement common helpers for command wrappers. This assumes that the command wrapper is a struct
+/// containing a `cmd: Command` field and a `output` function. The provided helpers are:
+///
+/// 1. Generic argument acceptors: `arg` and `args` (delegated to [`Command`]). These are intended
+///    to be *fallback* argument acceptors, when specific helpers don't make sense. Prefer to add
+///    new specific helper methods over relying on these generic argument providers.
+/// 2. Environment manipulation methods: `env`, `env_remove` and `env_clear`: these delegate to
+///    methods of the same name on [`Command`].
+/// 3. Output and execution: `output`, `run` and `run_fail` are provided. `output` waits for the
+///    command to finish running and returns the process's [`Output`]. `run` and `run_fail` are
+///    higher-level convenience methods which waits for the command to finish running and assert
+///    that the command successfully ran or failed as expected. Prefer `run` and `run_fail` when
+///    possible.
+///
+/// Example usage:
