// DomainRemoveCommand lists domains.
var DomainRemoveCommand = &cli.Command{
	Name:      "remove",
	Usage:     "Remove domain name records for a zone",
	Aliases:   []string{"rm"},
	ArgsUsage: "<zone> <type> <name>",
	Flags: []cli.Flag{
		internal.DNSProviderFlag,
	},
	Description: `
This command removes a new domain name record for a specific zone.

You must specify a zone (e.g. example.com) under which your domain name records
are listed. This zone must already be created on your provider account.

The "<id>" can be retrieved by running "abra domain list <zone>". This can be
used then in this command for deletion of the record.

Example:

    abra domain remove -p gandi foo.com A myapp

Which means that the domain name record of type A for myapp.foo.com will be deleted.
