 	Create a template for customizing the login page

 	This command creates a basic template to use as a starting point for
 	customizing the login page. Save the output to a file and edit the template to
 	change the look and feel or add content. Be careful not to remove any parameter
 	values inside curly braces.

 	To use the template, set oauthConfig.templates.login in the master
 	configuration to point to the template file. For example,
 
 	    oauthConfig:
 	      templates:
 	        login: templates/login.html
