[wp-hackers] Get list of roles

[Ryan Bilesky]

thats interesting.  I was just going to do this to keep administrator out of
the loop, since no matter what admins should have all of my custom
capabilities.

global $wp_roles;
$roles = $wp_roles->get_names();
foreach ($roles as $role_name=>$display_name) {
 if ($role_name != 'administrator') {
  // Show cap settings for role
 }
}
