eitherIO : HasIO io => (err -> PackErr) -> io (Either err a) -> EitherT PackErr io a

finally : Monad m => EitherT err m () -> EitherT err m a -> EitherT err m a

sysAndLog : HasIO io => Env => LogLevel -> CmdArgList -> EitherT PackErr io ()

  Tries to run a system command while logging its output.

Visibility: export

sysWithEnv : HasIO io => CmdArgList -> List EnvVar -> EitherT PackErr io ()

  Tries to run a system command prefixed with the given
  environment variables.
  
  Note: In case of an error, the environment will not be part
  of the command listed in the error message. This is a
  deliberate choice to declutter Idris output in case of a
  failed build. If the environment should be included in the
  error message, just prefix `cmd` accordingly and use `sys`.
