	Short: `Create a new remote with name, type and options.`,
	Long: `
Create a new remote of <name> with <type> and options.  The options
should be passed in in pairs of <key> <value>.

For example to make a swift remote of name myremote using auto config
you would do:

    rclone config create myremote swift env_auth true

Note that if the config process would normally ask a question the
default is taken.  Each time that happens rclone will print a message
saying how to affect the value taken.

If any of the parameters passed is a password field, then rclone will
automatically obscure them before putting them in the config file.

So for example if you wanted to configure a Google Drive remote but
using remote authorization you would do this:

    rclone config create mydrive drive config_is_local false

var configUpdateCommand = &cobra.Command{

Update an existing remote's options. The options should be passed in
in pairs of <key> <value>.

For example to update the env_auth field of a remote of name myremote
you would do:

    rclone config update myremote swift env_auth true

If any of the parameters passed is a password field, then rclone will
automatically obscure them before putting them in the config file.

If the remote uses oauth the token will be updated, if you don't
require this add an extra parameter thus:

    rclone config update myremote swift env_auth true config_refresh_token false

Update an existing remote's password. The password

For example to set password of a remote of name myremote you would do:

    rclone config password myremote fieldname mypassword

This command is obsolete now that "config update" and "config create"
both support obscuring passwords directly.
