   I'm looking for pointers on how to add a capability to a specific user role without using plugins.

   For example if I'd like Editors to be able to edit and add users, I thought something like:
   

   function give_user_edit() {
   	if(current_user_can('edit_others_posts')) {
   		global $wp_roles;
   		$wp_roles->add_cap('editor','edit_users' );
   		$wp_roles->add_cap('editor','create_users' );
   	}
   }
   add_action('admin_init', 'give_user_edit', 10, 0);

   Would work, but it seemed to add the capabilities for everyone.

   Any pointers greatly appreciated.

   This is a pointer - it gets the capabilities from say Administrator, then subtracts the ones it doesn't want, then assigns the new capabilities to a new role.

   I'm still struggling myself :-)

   // THIS WORKS  http://sillybean.net/wordpress/users-and-roles/creating-roles/
   $newrole = get_role('administrator'); /*choice of Administrator, Editor, Author, Contributor, Subscriber - http://codex.wordpress.org/Roles_and_Capabilities*/
   
   $caps = $newrole->capabilities;
   
   // Remove the stuff we don’t want in the new role.
   unset($caps['activate_plugins']);
   unset($caps['edit_plugins']);
   unset($caps['update_plugins']);
   unset($caps['delete_plugins']);
   unset($caps['install_plugins']);
   unset($caps['edit_users']);
   unset($caps['delete_users']);
   unset($caps['create_users']);
   unset($caps['import']);
   
   // Add the new role.
   add_role('Designer', 'Designer', $caps);

   I've gone the easy route - props to this perfect little plugin:
