This file provides a preprocess function on behalf of the User Points module.

Code

  // userpoints_get_current_points() gets $uid = 0, it returns the points

  // the permission 'view own userpoints' if the user if viewing his own points.

    // cached in userpoints_get_current_points() but to save count(userpoints_get_categories())
