Usage: consul configtest [options]

  DEPRECATED. Use the 'consul validate' command instead.

  Performs a basic sanity test on Consul configuration files. For each file
  or directory given, the configtest command will attempt to parse the
  contents just as the "consul agent" command would, and catch any errors.
  This is useful to do a test of the configuration only, without actually
  starting the agent.

  Returns 0 if the configuration is valid, or 1 if there are problems.
